Type GL309 Introduction

1.0 Introduction
AREVA T&D bases its position as a global leader in circuit breaker and circuit switcher development on
the operating experience that we have accumulated from the more than 60,000 circuit breakers and
circuit switchers with spring and hydraulic operating mechanism that are in operation throughout the
world. SF6 circuit switchers from AREVA T&D demonstrate a high level of reliability on a daily basis.
Even under extreme conditions such as those that prevail in areas with high seismic activity or in the
tropical regions of the world, our customers can count on AREVA T&D circuit switchers.
All circuit switchers described in this manual are factory tested and designed to meet specific customer
requirements and all applicable ANSI, IEEE, IEC, and NEMA standards at the time of manufacture.
There is no assurance that these products meet all state and local codes because the code
requirements vary so greatly.

An ISO 9001:2000 certified quality management system and ISO 14001-certified environmental
management govern the entire development and production process for AREVA T&D high voltage
circuit switchers. This guarantees a high quality product as well as compliance with the rated values
obtained in type tests.

1.1 Using this Instruction Manual

AREVA T&D designs SF6 circuit switchers to allow long intervals between maintenance. The term "SF6
circuit switcher" includes all associated equipment mounted on the frame and foundation of the circuit
switcher. Appropriate care and close observance of instructions in this manual will assure the reliability
of the circuit switcher.

and reconditioning according to the guidelines in this manual. The maintenance and reconditioning
recommended encompasses only those parts that are subject to wear and aging.

IMPORTANT
AREVA specialists should carry out major maintenance and reconditioning. Your service personnel
can be thoroughly trained in courses offered by AREVA.

Local environment and switcher applications must be considered in your maintenance and
reconditioning programs, including such variables as ambient temperatures, actual continuous current,
number of operations, type of interrupting duty, and any unusual local conditions such as corrosive
atmosphere or major insect problems. The AREVA maintenance program considers these variables by
offering appropriate inspection, maintenance and reconditioning intervals.

! DANGER
This circuit switcher contains charged springs, and high-pressure SF6 gas. Before performing any
service on this equipment, read the applicable sections of the instruction manual – particularly Chapter
2, Safety.

When operating equipment in extreme ambient conditions, we advise that you increase the frequency
of inspection and maintenance intervals. Such conditions include:
• Permanent high ambient temperature
• Abrasive dust in the atmosphere
• High dust content atmosphere
• Permanent high humidity
• Corrosive gas or vapors in the atmosphere

developments. No claims can be asserted from the statements, figures, or descriptions in this manual.

1.3 Device Descriptions

The experience that has been acquired with the well known S1, HGF and FXT types of switchgear have
been systematically and effectively utilized to create the improved design of GL309 type circuit
switchers. Consequently, these circuit switchers satisfy demands for high reliability and guarantee
optimum substation availability. The live tank circuit switchers demonstrate significant product
improvements based on experience with more than 60,000 self-blasting SF6 circuit switchers in use
throughout the world in combination with AREVA T&D’s spring mechanisms. The spring mechanism is
new and improved due to experience accumulated with over 70,000 AREVA T&D spring mechanisms
in service. The key benefits of this circuit switcher are:
• Third-generation self-blast interrupter chamber
• Design based on the proven reliability of its predecessor, the S1
• Pre-set at factory before shipping, which means that no adjustments necessary during
installation and commissioning
• Designed for ease of maintenance

 Introduction to Type GL309 Circuit Switchers

1.3.1 Pole Unit

Each pole column consists of a support porcelain bushing for insulating operational voltage to ground
and a chamber insulator in which the interrupter unit is located. The pole columns and the SF6 piping
form a common gas compartment. The movable contacts of the interrupter unit connect to the
mechanism by the insulating rods, the torque shafts, and the pole column levers, and by the connecting
rods in the base frame.

1.3.2 Operating Mechanism

The mechanism consists of a self-supporting steel structure. The doors, floor, rear panel, removable
side panels, and roof are made of aluminum sheet.
For storing the required operating energy, helical compression springs are charged by an electric motor
via a gear unit. Electrical actuation of the closing and opening coils causes latches to be unlatched,
which releases the energy of the springs for operating purposes. The spring energy transmits to the
pole columns by the lever on the rear of the operating mechanism, the drive rod, and the connecting
rods.

1.3.3 SF 6 Gas Monitoring System

This paragraph describes the standard SF6 gas monitoring system, incorporating a WIKA density
monitor. Consult the drawings for your switcher to identify your particular system and any optional
equipment (See Chapter 7).
• The standard AREVA Type GL309 circuit switchers uses a temperature compensated gas
density monitor, which will provide an alarm when the density in the pole units falls below 5.4
bar (78.3 psig at 20°C) and operational lock-out at 5.1 bar (74.0 psig at 20°C).
• After examining your SF6 gas monitoring system, refer to the appropriate paragraphs in the
following pages.
• The WIKA temperature-compensated density gauge is factory adjusted and cannot be adjusted
in the field.
• No maintenance is required on a WIKA density monitor. No replacement parts are listed except
the complete SF6 temperature compensated gas monitor.
• The opening and closing points of the pressure switches must be in accordance with the
requirements for each switch application.
• Quick-connect valves are located at each tank so each tank can be isolated easily.

1.3.4 SF 6 Gas Density Monitor

The standard WIKA gas density monitor is a temperature-compensated device. Due to the temperature
compensating mechanism of the gauge, the monitor will not respond to normal pressure changes in the
SF6 gas that are caused by changes in the ambient temperature. The monitor will only respond to
changes in density of the SF6 gas, for example, due to a leak in the system or during filling of the gas
system.
The temperature-compensated gas monitoring system is furnished with internal electrical contacts to
provide an alarm when the SF6 gas density in the pole units falls below 5.4 bar (78.3 psig at 20°C), and
to lockout the switcher at 5.1 bar (74.0 psig at 20°C). If you suspect leaks, the switcher should be
isolated from the system and inspected for leaks. If you detect leaks, repair the leaks and bring the gas
up to normal operating pressure before returning the switcher to service.

Type GL309 Introduction

If a customer requested non-temperature compensated pressure gauge is provided with the SF6 gas
monitoring system, the chart shown in Figure 1-2 must be used to determine the proper SF6 gas
pressure at a given temperature.
In addition, if a customer requested the -40°C rating option, the temperature-compensated gas
monitoring system is furnished with alternate alarm and lockout pressure settings. The internal
electrical contacts will provide an alarm when the SF6 gas density in the pole units falls below 3.6 bar
(52.2 psig at 20°C), and to lockout the switcher at 3.3 bar (47.9 psig at 20°C).
SF6 in the gaseous state will show a change in pressure as its temperature is changed. This is
represented by the curve shown in Figure 1-2. The graph shows the normal SF6 pressure in the circuit
switcher over the rated temperature range of the circuit switcher.

1.3.5 SF 6 Gas Policy

The Intergovernmental Panel on Climate Change identified SF6 as a "greenhouse gas" with the
potential to contribute to global warming.
Do not deliberately release SF6 gas into the atmosphere.
Carefully follow gas-handling procedures described in the instruction manual to limit the release of SF6
gas over the life of the circuit switcher. Utilize gas handling and reclaiming equipment.

GL09-IM INSTRUCTION MANUAL

details.

NOTE
Presents instructions, practical tips, comments, or background information.

2.1 Safety Precautions – General

Closely adhere to all instructions and service advisories. Study instructions and advisories thoroughly
before you begin any installation, operation, or maintenance.
Thoroughly instruct all personnel associated with installation, operation and maintenance of power
circuit switchers regarding power equipment in general and on the particular model of switcher that they
are working with. Closely study and follow instruction books and service advisories.
Maintenance programs must be well planned and carried out consistent with both customer experience
and manufacturer’s recommendations including service advisories and instruction books. Good
maintenance is essential to switcher reliability and safety.
Consider the following recommendations in your safety program. These recommendations are not
intended to replace your responsibility for devising a complete safety program and must not be
considered as such. They are suggestions to cover the more important aspects of personnel safety
related to circuit switchers. AREVA neither condones nor assumes any responsibility for user practices,
which deviate from these recommendations. Your company safety regulations always take precedence.

2.2 Safety Precautions – Specific

! DANGER
When dealing with circuit switchers, it is critical to remember that you are dealing with high voltages,
high gas pressures, toxic by-products, and moving machine parts. Do not take shortcuts or ignore
safety warnings and practices!

a) Do Not work on an energized switcher! If work has to be performed on the switcher, take it out
of service, open the switcher, open the disconnect switches at each side of the switcher, then
discharge the springs and ground each phase.
b) Do Not work on any part of the de-energized switcher until you disconnect all control and heater
power.
c) Do Not disassemble any portion of the gas system of the de-energized switcher until that
portion of the system has had the pressure reduced to ambient pressure by utilizing proper gas
handling equipment. After reducing the gas pressure to zero, cautiously remove covers, tubes,
fittings, etc.
d) To prevent over pressurizing the switcher, always use an SF6 regulator when filling or adding
SF6 to the switcher. Take precautions to protect personnel against sudden gas release from
accidental breakage of adjacent parts.
e) Never invert the gas bottle: this will release liquid SF6 into the switcher, will over pressurize the
switcher, and may cause the pressure relief device to release, requiring service and
replacement of parts.
f) Only skilled and knowledgeable personnel are permitted to service the operating mechanisms.
Take particular care to keep personnel clear of mechanisms that are to be operated or
discharged. This instruction manual provides information on mechanism operations.

! CAUTION
The circuit switcher is equipped with a stored energy mechanism for opening and closing operations.
In the closed state, the mechanism stores enough energy for an O-C-O operating sequence. To
remove stored energy from the mechanism, remove all control voltage from the motor. Then open and
close the switcher until all stored energy is released.

g) If there is any evidence of deterioration in the switcher dielectric capability, de-energize the
switcher by remote switching of back-up circuit switchers and isolated by disconnect switches.
h) Make Operational tests and checks after switcher maintenance to ensure that the switcher is
capable of properly operating. The extent of such tests and checks must be consistent with the
level of maintenance performed.

2.3 Handling SF6 Gas

! CAUTION
Never intentionally release SF6 into the atmosphere.
(Refer to Addendum A for detailed information about SF6)

When opening an SF6 filled pole, consider the following while handling SF6 gas:

INSTRUCTION MANUAL GL09-IM

December 7, 2006
Chapter 2, Page 4
AREVA T&D Circuit Switchers Chapter 2 Rev. 0
Type GL309 Safety

1. Sulfur Hexafluoride (SF6) is a colorless and odorless gas. Pure SF6 is non-poisonous; therefore,
no risk classification needs to be followed. Refer to the Material Safety Data Sheet (MSDS) in
Attachment A for complete details.
2. The maximum allowable concentration at a place of work, assuming that a person spends 8
hours per day there, is 1000 PPM (or 0.1%) by volume. This low value is the standard adopted
for all gases considered harmless, but not normally present in the atmosphere.
3. Under the influence of an arc, SF6 decomposes into products, which have varying toxicities.
They may irritate mucous membranes, respiratory tracts, or other unprotected skin. You can
recognize even the smallest amounts of gaseous decomposition products almost immediately
by their strongly pungent, sulfurous odor, generally before the danger of contamination arises.
4. It is necessary for maintenance personnel to follow these safety precautions in addition to all
safety regulations prescribed by their employer.
5. Do not agitate SF6 decomposition by-products unnecessarily.
6. Remove SF6 decomposition by-products immediately after opening the switcher (pole) to
prevent moisture combining with the by-products.
7. Use a suitable vacuum cleaner with dust filter, and wipe off the remaining decomposition by-
products with a piece of lint free cloth.
8. To neutralize SF6 by-products on desiccant and used cleaning cloths, soak them in a 3% soda
solution for 24 hours, or dispose of them as hazardous materials.

2.4 Protective Gear for Handling SF6 Gas

! WARNING
Sulfur hexafluoride (SF6) is potentially dangerous because of the toxicity of the gas by-products and
possible suffocation in low-lying places in enclosed areas.

1. Eating, drinking, or smoking, as well as food storage, are strongly discouraged inside rooms
with SF6 installations. These activities are prohibited during maintenance work, when the
interrupter enclosures are opened.
2. Only maintenance personnel who are necessary to carry out the work are allowed to be in the
work area.
3. Avoid direct contact with parts that were in contact with the insulating gas.
4. Do not allow the powdery decomposition products to touch exposed skin.
5. Ensure more than “sufficient” room ventilation.
6. Maintenance personnel handling used SF6 gas, must be equipped with the following personal
safety gear:
• Appropriate gas mask or breathing equipment. The best choices are a full gas mask or a
gas mask, breathing equipment, and gas-tight safety glasses.
• Dust tight acid resistant protective overalls (disposable).
• Rubber gloves or disposable gloves.
• Rubber boots or disposable boots.
7. After completing the gas handling procedure, thoroughly wash the gas mask and breathing
equipment, safety glasses, rubber boots and rubber gloves with water.

Type GL309 Instructions on Handling SF6 Gas and By-products

A.1 SF6 Gas Overview

As with various other chemicals utilized frequently in industry, SF6 gas and its decomposition products
do not pose injury or health related issues if handled properly. Health related hazards exist in particular
situations and arise due to careless or improper handling. The quality of SF6 gas conforms to the
recommendations of IEC 376 or ANSI/ASTM D2472-71 (1980).
SF6 is approximately five times heavier than air (one of the heaviest known gases) and tends to
accumulate in low areas. Although pure SF6 is nontoxic, it can displace oxygen and cause
asphyxiation. Therefore, it is necessary to exercise caution when working in circuit breaker tanks, circuit
switcher pole columns, or other enclosed areas where SF6 may accumulate.
Carefully followed gas handling procedures described in the instruction book to limit the release of SF6
gas over the life of the circuit switcher. Utilize gas handling and reclaiming equipment. Used SF6 must
either be recycled or destroyed.
AREVA designs, manufactures and factory tests circuit breakers, circuit switchers, and GIS to be free
of leaks. AREVA warrants a gas leakage rate of less than 1% per year on all SF6 equipment. If leaks
develop in service, take appropriate action to locate and eliminate SF6 gas leaks.

! WARNING
Outdoor use of pure SF6 is safe. However, SF6 decomposition products require special protective
measures.

! CAUTION
The maximum permissible moisture content in SF6 gas must not exceed 125 ppmv upon filling.
Moisture can react with SF6 under the influence of electrical discharges to form toxic and corrosive
compounds through hydrolysis.

A.2 Properties of SF6 Gas

Sulfur hexafluoride (SF6) is an extremely stable gas that is chemically inert under normal conditions.
The strong electron affinity of the SF6 molecule, along with its relatively large physical size and mass
(molecular weight of SF6 = 146 g/mol), gives the gas excellent insulating properties, making it
particularly suitable as a dielectric for high and medium voltage applications. The breakdown voltage of
SF6 at 1 bar (14.5 psig) is 250-300% higher than air or nitrogen, while arc-quenching times are 100
times faster than air.
Furthermore, SF6 regenerates itself spontaneously following disassociation and ionization due to an
electric arc produces less pressure increases than other gases and has excellent heat transfer
characteristics. These properties make SF6 the ideal insulating medium for today’s high capacity
switches and circuit breakers, as well as for transformer and transmission line applications.
Although SF6 is an ideal insulating medium, it possesses one disadvantage; it has a relatively high
liquefaction point. Liquefaction of SF6 occurs between -10°F and -30°F, depending on the density of the
gas (refer to Figure A-1). This tends to lead to conflicting requirements of SF6. Higher pressures and
densities increase its dielectric strength and its arc-quenching properties, but also increase the
liquefaction temperature. In regions where the ambient temperature falls below -10°F, even for short
durations, provide supplemental means of maintaining SF6 temperatures above -10°F.
The Intergovernmental Panel on Climate Change identified SF6 as a “greenhouse gas” with the
potential to contribute to global warming. Therefore, never deliberately release SF6 gas into the
atmosphere. Current international standards require that leakage losses from SF6 equipment must not

GL09-IM INSTRUCTION MANUAL

for Type GL309 Circuit Switchers

exceed 1% per year. SF6 installations can meet this requirement, and any more stringent standards
that may propagate in the future by using appropriate handling procedures and on-site monitoring,
reclamation and incineration equipment now available.

A.3 Health Risks for Pure SF6

! WARNING
There is danger of suffocation due to lack of oxygen if the SF6 concentration exceeds 35 percent by
volume in air. Such concentrations can occur in non-ventilated open SF6 installations, and at ground
level of narrow compact rooms, as well as in spaces below ground level (e.g. basements, cable
ducts). If SF6 gas escapes without being able to mix turbulently with ambient air, it may, because of its
high density, accumulate at floor level and enter lower located rooms. Once SF6 gas has mingled with
air it will not collect in low areas.

Type GL309 Instructions on Handling SF6 Gas and By-products

Pure sulfur hexafluoride (SF6) gas is chemically very stable, inert, almost water insoluble, non-
flammable, non-poisonous, odorless, colorless and heavier than air (approximately 5X by weight). SF6
is an insulating and cooling gas of high thermal stability and dielectric strength.
SF6 is nontoxic; therefore, no risk classification needs to be specified. Refer to Attachment A, the
Material Safety Data Sheet (MSDS), for complete details.
The maximum allowable SF6 concentration at a place of work, assuming that a person spends 8 hours
per day there, is 1000 ppm (or 0.1 %) by volume. This very low value is the standard value adopted for
all gases considered harmless, but not normally present in the atmosphere. In the case of SF6, it is
more than two orders of magnitude lower than the danger level.
Clean, pure SF6 gas contains no contaminants, which are detrimental to health; however, there exists a
risk of asphyxiation as discussed above.

A.4 Decomposition Products of SF6

! WARNING
SF6 decomposition products are toxic in various ways. They can result in skin, eye and mucous
membrane irritations, and, when handled in large amounts, will lead to laryngeal and lung failure,
heart and circulatory collapse, as well as blackouts. Gaseous decomposition products, even in small
amounts, provide certain warning symptoms within seconds (for example, unpleasant, piercing odors,
and nasal, mouth, and eye irritations), before any actual poisoning takes place, which enables
personnel to withdraw to safety in time.

Under the influence of an arc, decomposition products are created which are partly toxic. The amounts
of decomposition products formed are proportional to the magnitude and duration of the arc, the degree
of the temperature increase, the design materials of the equipment and contaminants present such as
air and moisture.
Due to the resilient properties of SF6, a large part of the decomposed gas recombines, upon cooling.
Reactions may occur, however, with other materials present in the equipment (e.g. with vaporizing
arcing contact material). This results in the formation of gaseous sulfur fluoride and solid metallic
fluoride powder. In the presence of oxygen or moisture, the development of hydrogen fluoride and
sulfur dioxide may occur. Solid byproducts, when present, can be observed in the form of white, grey,
or tan powders, and are irritating to exposed skin.
If moisture is present, corrosive electrolytes may form from the primary and secondary decomposition
products of SF6. These electrolytes may cause damage and operational failure in electrical equipment,
particularly to insulating surfaces such as glass and porcelain. Therefore, it is recommended to perform
circuit switcher maintenance on rain free days and days with low ambient humidity.
Adsorption can reduce moisture and SF6 decomposition products inside equipment to acceptable
levels. Materials such as alumina, lime, molecular sieves or combinations thereof are suitable for this
purpose. They adsorb the gaseous acid products effectively and practically irreversibly, and at the
same time ensure that the gas maintains a low dew point temperature.

A.5 Safety Precautions – Ventilation

! WARNING
With an SF6 concentration exceeding 35 percent by volume in air, there is danger of suffocation due to
lack of oxygen. Such concentrations can occur in unventilated open SF6 installations, and at ground
level of narrow compact rooms, as well as in spaces below ground level (for example, basements or
cable ducts). If SF6 gas escapes without being able to mix turbulently with ambient air, it may,
because of its high density, accumulate at floor level and enter lower located rooms. Once SF6 gas
has mingled with air, it will not collect in low areas.

In installations located at ground level, intermingling of SF6 and air produced by natural circulation is
adequate. About 50% of the ventilating airflow cross-section should be located as close as possible to
ground level. In the case of breakdowns, provide forced ventilation.
In installations located below ground level, mechanical ventilation (forced ventilation) is required. The
volume of gas, the gas losses, and the size of the room could result in SF6 collecting in sufficient
quantities to cause asphyxiation. In the case of forced ventilation, SF6 contaminated air must be
collected as close to ground level as possible.
Spaces lying below SF6 switchgear installations (for example, shafts, cable ducts, sumps, and pits)
which are connected to rooms of the installation must be adequately ventilated or sealed-off in such a
manner that SF6 cannot collect in dangerous amounts.

A.6 Recommended Equipment for SF6 Handling

The following equipment is recommended as protective gear for persons working in circuit breaker
tanks, circuit switcher pole columns, or other restrictive areas where SF6 may accumulate, and where
decomposition byproducts may be present:
• Forced air type respirator with a minimum of 50 feet of supply hose.
• Filtered air supply capable of supplying sufficient ventilation.
• Full-face respirator with filter cartridges for organic vapors and acidic gases.
• Portable compressed air supply.
• Chemical resistant type industrial goggles.
• Disposable hooded coveralls, non-permeable acid resistant paper type with nylon reinforcement
material. Preferably, industrial grade with elastic ankle and wrist grips that overlap boots and
gloves.
• Gloves: rubber / neoprene, non-disposable type that cover to the elbow.
• Boots: rubber, non-disposable, over the shoe type that extends to the knee.
• Wet / dry type vacuum cleaner with non-metallic attachments and a filter capable of filtering
particles to at least 1µm in size.
• Lint-free cloth and cleaning solvent such as denatured ethyl alcohol.
• Neutralizing agent such as sodium carbonate or lime (calcium hydroxide).

A.7 Occupying and Entering Rooms with SF6 Switchgear Installed

! CAUTION
If there is an unpleasant, piercing odor from SF6 decomposition products in a room with SF6
switchgear installed, vacate the room immediately. Do not enter the room unless you are wearing
suitable oxygen masks or after thoroughly ventilating the room.

If there is a disturbance in the installation and you encounter concentrations of SF6 gas in hazardous
amounts (risk of suffocation) due to the gas volume and size of the room, enter the room only after
thoroughly airing it. Entrance is only permitted to persons wearing oxygen masks operating
independent of the ambient air, or alternatively, after establishing that the ambient air contains at least
17% oxygen.
Rooms located below the switchgear installation and associated with the plant may only be entered by
a team wearing suitable oxygen masks or after thoroughly ventilating the room.

A.8 Working on SF6 Switchgear

A.8.1 Fundamental Rules

Appropriate sections of the Instruction Manual give instructions for performing work on SF6 switchgear.
Only open switchgear after completing scavenging operations to remove the SF6 gas.
Maintenance personnel must follow these safety precautions in addition to all safety precautions
established by their employer.
• Ensure that there is adequate ventilation (natural or mechanical).
• Do not agitate SF6 decomposition by-products unnecessarily.
• Remove SF6 decomposition by-products immediately after opening the switcher pole unit to
prevent moisture combination with by-products. Use a suitable vacuum cleaner with dust filter
and wipe off remaining decomposition by-products with a piece of lint free cloth.
• To neutralize SF6 by-products (arc products), on the desiccant and used cloths, soak them in a
3 percent soda solution for 24 hours. To verify the degree of neutralization after 24 hours, add
additional soda to the solution. If the solution is neutralized it will not effervesce; if it does
effervesce repeat the neutralization process.

A.8.2 Removal of SF 6 Gas from Equipment

! CAUTION
There is a possibility of a dangerous situation leading to possible injury and/or damage to the
equipment.

• De-energize apparatus, switch-off where applicable and ground to earth.

• Connect the service unit to the gas-filling nipple by means of a fill hose. Employ the use of an in-
line adsorbent filter to remove any decomposition by-products or contaminants such as oxygen
or moisture.
• Refill the circuit breaker tank or circuit switcher pole columns, if possible, with nitrogen or dry
compressed air to the rated pressure (flush) and subsequently discharge the gas outdoors
through an adsorbent filter.

A.8.3 SF 6 and the Environment

SF6 is critical to the reliable distribution of electricity. Therefore, it is essential for users to recognize the
importance of responsible use and careful management. SF6 possesses powerful greenhouse gas
characteristics. It posses a global warming potential of approximately 24,000 times that of carbon
dioxide over a 100-year time horizon, with an atmospheric residency of more than 3,000 years.
Although SF6 has these attributes, substantial evidence exists, which indicates that SF6 has a negligible
impact on the global environment. Because SF6 is manufactured rather than naturally occurring and
because of its long lifetime, take precautions to minimize the quantity of SF6 released into the
atmosphere.

A.8.4 Opening the Apparatus

! CAUTION
Before opening the apparatus, use an HF monitor to sample the switcher gas to detect possible
toxins.

• Open the SF6 switchgear only after evacuating the gas and reducing the pressure inside the
apparatus to atmospheric pressure.
• Either place the ventilation system in operation or ensure that fresh air circulates in some other
manner (for example, natural turbulence) when switchgear containing decomposition products is
opened.
• Wear a suitable fresh air breathing apparatus if there is even the slightest possibility that
personnel working on the equipment may be in danger through inhalation of hazardous amounts
of gas or vapor from powdery decomposition products. (For example, wide-range masks, type
72 (RIVA) with filter B2P2 from AGA Company or equivalent from “Draeger”). Monitor the levels
of the oxygen content to avoid the danger of asphyxiation)!
• Wear hooded, disposable, non-permeable, acid resistant coveralls, made of paper with a nylon
type reinforcement material, when working on open SF6 switchgear that contains powdery
decomposition products. After completing work remove coveralls and dispose of as prescribed.
• Avoid stirring-up dust and powder from SF6 switchgear. Difficult-to-remove dust can be removed
with dry non-fibrous rags. Use a vacuum cleaner to remove loose dust. The vacuum cleaner
filter should be able to retain particles of at least 1µm in size.
• Items (such as rags, vacuum cleaner and filter, disposable coveralls, gloves, etc.) which come
in contact with the decomposition products must be collected and neutralized so that the dust
cannot be transferred, before disposing of these items. Or they may be disposed of as
hazardous materials. (Note: California requires special permits to treat hazardous waste.)
• Under all circumstances ensure that the decomposition products do not come in contact with
skin, eyes, clothes, or that they are not swallowed or inhaled. Pay special attention to personal
hygiene, clothes and work bench. Dust or powder that comes in contact with skin must be
washed away with plenty of clean water. It is advisable to wash face, neck, arms, and hands
with soap and plenty of clean water before work breaks and after stopping work.
• Avoid eating, drinking, smoking, or storing foods in rooms or outdoors near to opened SF6
switchgear, which may contain arc-decomposed powder.

A.9 Summary of Important Safety Instructions

! CAUTION
Although pure, non-contaminated SF6 gas is non-poisonous, electrical discharges and fault-switching
arcs will give rise to different grades of toxic decomposition products. In small amounts gaseous
decomposition products – within seconds and before any poisonous effects can take place – produce
warning symptoms, such as an unpleasant piercing odor or nasal, mouth and eye irritations, which
enable working personnel to withdraw to safety.

Solid decomposition products (powdery residues from switching) can cause skin irritations. SF6 is about
five times heavier than air, and in the absence of turbulence, results in the gas collecting just above
ground level. It may cause suffocation through oxygen deprivation when working indoors or in areas
where the gas can accumulate.

Therefore, observe the following instructions while performing maintenance work or inspection in SF6
substations and on SF6 switchgear:
• As soon as an unpleasant, piercing odor from decomposition products becomes perceptible,
immediately leave the substation room. Enter the room only after thorough ventilation or when
wearing suitable oxygen breathing masks (with filtering or forced air devices).
• After disturbances, enter the substation room only after having thoroughly ventilated the room,
or when wearing oxygen breathing masks that operate independent of ambient air. Alternatively,
after verifying by measurement that the ambient air contains at least 17% oxygen by volume,
especially if one has to reckon with the concentration of SF6 in hazardous amounts.
• Enter rooms located below, and connected with the substation-rooms after thorough ventilation
only, or when wearing oxygen breathing masks which operate independent of the ambient air,
or alternatively, after having verified by measurement that the ambient air contains at least 17%
oxygen by volume.
• Ensure that the room ventilation operates satisfactorily while performing maintenance on SF6
switchgear (discharging and filling of gas, opening and cleaning of equipment).
• Before entering SF6 switchgear enclosures, which contain powder deposits, wear dust-proof
(non-permeable) protective coveralls and suitable oxygen breathing masks (operating
independent of ambient air or, after having verification from measurement that there is adequate
oxygen, masks containing a filter device) as well as protective spectacles.
• When working on opened SF6 switchgear, protect skin against contact with decomposition
residue and avoid swallowing or inhaling gas. Ensure body, clothing, and workbench
cleanliness. Wear disposable work-coveralls, and after completing work, discard appropriately.
• Wash skin that comes in contact with powder deposits with plenty of water. Before work-breaks
and after work, wash your face, neck, arms and hands thoroughly with soap and plenty of water.
• Do not stir up powder deposits resulting from arc switching. Remove sticky powder with dry
rags. Use suitable vacuum cleaner with paper-filter to remove loose powder. Handle the powder
such that the deposits do not spread. Before discarding used items and filter-bags, neutralize
the contaminated items.
• Items (such as rags, vacuum cleaner and filter, disposable coveralls, gloves, etc.) that come in
contact with the decomposition products must be collected and neutralized so that the dust
cannot be transferred. Before disposing of these items, neutralize them in a 3 percent soda
solution for 24 hours. To verify the degree of neutralization after 24 hours, add additional soda
to the solution. If the solution is neutralized it will not effervesce, if it does, the neutralization
process is to be repeated. (Note: California requires permits to treat hazardous waste.)

! CAUTION
1. Do not eat, drink, store foods, or smoke inside rooms with SF6 installations, especially during
maintenance work, when the interrupter enclosures are opened.
2. Avoid direct contact with parts that were in contact with the insulating gas.
3. Do not allow the powdery decomposition products to touch exposed areas of the body.
4. Ensure sufficient ventilation of the room.
5. Only maintenance personnel who are necessary to carry out the work should be in the work area.
6. When handling used SF6 gas, maintenance personnel should be equipped as follows:
• Appropriate gas mask or breathing equipment. The best choice is full-face gas mask, or a gas
mask and breathing equipment plus gas-tight safety glasses.
• Dust tight, acid resistant protective coveralls (disposable).
• Rubber gloves or disposable gloves
• Rubber boots or disposable boots
• After completing work, wash the gas mask and breathing equipment, safety glasses, rubber
boots and rubber gloves thoroughly with neutralizing solution and drinkable water.

Type GL309 General Characteristics

3.1 Component Descriptions

GL309 type live tank circuit switchers consist of three pole columns on one common structure, a
mechanism, and a controls cabinet. The following sections briefly describe each of these items

Figure 3-1: General Circuit Switcher Outline (Rigid Conduit Option Not Shown)
1 Pole Columns 4 Auxiliary Controls Cabinet
2 Base Frame 5 Supports
3 Spring Operating Mechanism 6 Interconnection Cables

3.1.1 Pole Unit

Each pole column consists of a support porcelain for insulating operational voltage to ground and a
chamber insulator in which the interrupter unit is located. The pole columns and the SF6 piping form a
common gas compartment. The movable contacts of the interrupter unit connect to the mechanism by
the insulating rods, the torque shafts, and the pole column levers, and by the connecting rods in the
base frame.
When the current is interrupted, a transition from the conductive to the insulating state occurs within a
few milliseconds. During the opening operation, an arc forms; it quenches by the gas flow within the
interrupter unit.

GL09-IM INSTRUCTION MANUAL

December 7, 2006
Chapter 3, Page 3
 General Characteristics of Type GL309 Circuit Switchers

3.1.2 Interrupters
The GL309 circuit switcher design incorporates interrupters housed in each pole unit that utilize third-
generation auto-puffer, energy-optimized, self-blasting principle. This allows for the optimization in the
use of the arc energy and enables the operation to be driven by a low energy spring mechanism
In the opening operation, the main contact system opens first. Then the arcing contacts open and an
arc forms. In the case of high current operations, the pressure for arc blow out in the pressure chamber
volume is generated by the arc itself in accordance with the self-blast principle. Immediately after the
contact rod leaves the nozzle restriction, SF6 gas flows out of the pressure chamber and thus quenches
the arc at the next current zero. The circuit switcher is now in the open position. In the case of low
current operations, the auxiliary puffer volume serves to generate the necessary quenching pressure.
Valves in the stationary piston and in the bottom of the pressure chamber volume control the type of
pressure generation.
The Interrupter unit is maintenance free for up to 10,000 operations or 40 years. No need for
replacement parts for over 40 years under normal conditions.

3.1.3 Base Frame

The base frame is constructed from fabricated steel sheet that is galvanized. There are closures
welded to the tank at each end. The base frame is ventilated in each corner to help remove
condensation.

3.1.4 Operating Mechanism

The mechanism consists of a self-supporting steel structure. The doors, floor, rear panel, removable
side panels, and roof are made of aluminum sheet.
For storing the required operating energy, helical compression springs are charged by an electric motor
via a gear unit. Electrical actuation of the closing and opening coils causes latches to be unlatched,
which releases the energy of the springs for operating purposes. The lever on the rear of the operating
mechanism, the drive rod, and the connecting rods transmit the spring energy to the pole columns.
Chapter 8 provides more in-depth information on your operating mechanism.

3.1.5 Auxiliary Controls Cabinet

The GL309 comes equipped with an auxiliary controls cabinet that will always be installed near ground
level. This ensures easy access to the customer controls, regardless of the switcher height. Like the
operating mechanism cabinet, the structure of this cabinet is fabricated from aluminum sheet. The
drawings for the controls are located in Chapter 7.

3.2 SF6 Gas Monitoring System

3.2.1 SF 6 Gas Density Supervision

The density monitor continuously measures the SF6 gas density in the circuit switcher gas system. In
order to ensure proper quenching of the arc and subsequently withstand the recovery voltage, the gas
density must not fall below the operational lockout value. To identify the characteristics of the gas
system, consult the drawings in Chapter 7 of this Instruction Manual.

INSTRUCTION MANUAL GL09-IM

December 7, 2006
Chapter 3, Page 4
AREVA T&D Circuit Switchers Chapter 3 Rev. 0
Type GL309 General Characteristics

3.2.2 SF 6 Gas Density Monitor

The gas density monitor features a color-coded density gauge dial (green-yellow-red), with three built-in
alarm contacts. The green zone indicates adequate pressure in the circuit switcher, yellow is the alarm
region, and red is lockout. A mechanical bimetal strip in the gauge provides temperature compensation.
The contacts are set at the factory and do not require field adjustment or periodic calibration. Replace
the SF6 gas density monitor as a complete unit only; maintenance is not possible.
If the circuit switcher pressure drops, the switcher should be isolated from the system and inspected for
leaks. If you detect leaks, repair them the bring the gas up to normal operating pressure at 20°C before
the switcher is returned to service. See the switcher nameplate for fill pressure.
SF6 in the gaseous state will show a change in pressure as its temperature is changed. This is
represented by the curve in Chapter 1.

3.2.3 SF 6 Gas Policy

! CAUTION
Refer to Chapter 2 for comprehensive safety information on handling SF6.

The Intergovernmental Panel on Climate Change identified SF6 as a “greenhouse gas” with the
potential to contribute to global warming. Never deliberately release SF6 gas to the atmosphere.
Carefully follow gas-handling procedures described in this instruction book to limit the release of SF6
gas over the life of the circuit switcher. Use gas-handling and reclaiming equipment.
AREVA designs, manufactures and factory tests circuit switchers to be free of leaks. AREVA warrants a
gas leakage rate of less than 1% per year on SF6 insulated equipment. If leaks develop in service, take
appropriate action to locate and eliminate SF6 gas leaks.

3.3 Electrical Operation

3.3.1 Closing Operation

When closing the switcher, a signal passes to the closing portion of the control circuit. Assuming gas
pressure is sufficient to prevent blocking, the switcher is in the open position, and the closing spring is
charged, the normal sequence of events is as follows:

NOTE
When a separate low pressure lock-out relay is used for Trip #1 and Trip #2, both trip circuits must be
enabled in order to pickup both lock-out relays for a closing operation (applies to normally energized
relays only).

1. The closing coil is energized.

2. The anti-pumping relay is energized. After a delay on pickup of 1/2 cycle, it will isolate the close
coil from the power source to prevent pumping.
3. The closing coil operates to release the mechanical latch allowing the closing spring to drive the
interrupters to the closed position, while at the same time charging the opening spring.
4. The auxiliary switch operates to the closed condition, closing all “a” auxiliary switch contacts and
opening all “b” contacts.

GL09-IM INSTRUCTION MANUAL

December 7, 2006
Chapter 3, Page 5
 General Characteristics of Type GL309 Circuit Switchers

5. For as long as the Close signal is maintained, the anti-pumping relay is sealed in through the
“52b” auxiliary contact locking in the anti-pumping relay, and thus preventing further energizing
of the closing coil.
6. When the Close signal is removed, the anti-pumping relay will be de-energized.
7. The main contacts will move to the full closed position. If a trip signal is present, the switcher will
then move to the full open position, demonstrating the “Trip-Free” function of the mechanism.

3.3.2 Opening Operation

1. When opening the circuit switcher, auxiliary and SF6 density relay contacts close in the trip
circuit, assuming the circuit switcher has sufficient SF6 pressure, and is in the closed position.
The trip coil energizes and releases the mechanical tripping latch to allow the opening springs to
operate, opening the circuit switcher contacts.
2. The trip coil is energizes and releases the mechanical tripping latch to allow the opening springs
to operate, opening the circuit switcher contacts.
3. The 52a auxiliary switches remove the voltage from the trip coils when the auxiliary switch
moves to the Open position.
4. If the switcher receives a trip (open) signal while the switcher is closed and the closing signal is
still impressed on the close circuit, the switcher will open but will not close again. The anti-pump
feature of the circuit prevents this due to the anti-pumping contact that prevents a continued
closing signal from energizing the closing coils.

! CAUTION
Interrupt current through the coils immediately by the switcher auxiliary switch contacts to avoid
damage to the coils.

3.4 Mechanical Operation

A stored energy operating mechanism drives the mechanical linkages and components necessary to
operate the circuit switcher. You may operate the switcher by energizing the trip coil momentarily to
open or by energizing the closing coil momentarily to close.

3.4.1 Closing Operation

• When the closing coil energizes, the armature is picked up, and the closing latch releases. The
closing latch releases the closing spring, and thereby, the closing cam, which transfers energy
to the main operating shaft of the mechanism.
• Through a series of linkages and levers, the main operating shaft drives the circuit switcher
interrupter units into the closed position, while at the same time charging the opening spring.
• When the closing operation is completed, the main operating lever of the mechanism will have
been driven out and held in the closed position by the tripping latch.
• The oil dashpot has a minimal damping effect during closing. The main contacts of the circuit
switcher use the energy of the closing spring to drive to the closed position, and to charge the
tripping spring.

INSTRUCTION MANUAL GL09-IM

December 7, 2006
Chapter 3, Page 6
AREVA T&D Circuit Switchers Chapter 3 Rev. 0
Type GL309 General Characteristics

3.4.2 Opening Operation

• When either or both of the opening coils are energized, the tripping latch releases, and the
opening spring drives the interrupter units into the open position via the main operating shaft of
the mechanism.
• The oil dashpot engages near the end of the opening stroke, controlling the opening speed and
providing damping action to prevent mechanical damage to the mechanism and interrupter
units.

3.5 Control Circuits

The control circuit of the switcher consists of the components necessary to energize the trip and close
coils on the mechanism controls, sense the position of the switcher and controls (open or closed) and
prevent switcher operations if unsafe or unsatisfactory conditions exist. The close or trip signals are
normally input from the overall power system control circuit but may be input from the control station on
the main panel in the electrical control cabinet. You may use the manual trip or external electrical trip to
open the switcher. This circuit may not be activated further until the 69 switch (when present) is reset.

! CAUTION
Only use the manual trip when the SF6 gas system is above minimum pressure.
A caution plate is located near the control as a reminder of the conditions for operation.

! CAUTION
Never operate the maintenance charging handle for manually charging the closing spring unless you
removed the control power.

! CAUTION
Do not operate the switcher unless SF6 gas pressure is above lockout (73.8 psig or 5.1 bar for -30°C
applications and 47.7 psig or 3.3 bar for -40°C applications).
For maintenance operation, push levers to Trip / Close.

Alarm circuits and other control arrangements are provided for specific switchers. Please refer to the
drawings in Chapter 7 (customer drawings and documentation) for a complete description of the
controls for your individual switcher.

5.0 General Instructions

Closely follow all instructions and service advisories. Thoroughly study these instructions before
beginning any installation, operation or adjustment.
Thoroughly instruct and supervise all personnel associated with the installation, operation or
maintenance of high voltage circuit switchers regarding high voltage equipment in general, and
specifically on the particular switcher model with which they are working.

5.1 Circuit Switcher Assembly

! CAUTION
Do Not charge the operating mechanism or operate the switcher until the mechanism is connected
and the switcher is charged with more than 73.8 psig (5.1 bar) of SF6 gas at 20°C for -30°C
applications or 47.7 psig (3.3 bar) of SF6 gas at 20°C for -40°C applications

• When the switcher is shipped completely assembled, the switcher pole units have been filled
with SF6 gas for transportation, approximately 2.9 to 7.3 psig (0.2 to 0.5 bar).
• The manufacturer has already made all adjustments. The drive rod of the mechanism has been
adjusted and locked with a locking compound.
• Pole columns and mechanism ship in the open position. The closing spring of the mechanism is
discharged.
• In the spring operating mechanism, the opening latch assembly has been secured for shipping
by a cable tie.
• Whenever the instructions call for "bolt and locking adhesive," always use the liquid locking
adhesive Loctite (blue).

NOTE
In the following sections, the side of the circuit switcher on which the mechanism is located is referred
to as the "front."

• No special tools are necessary for assembly of the circuit switcher.

• Check the size of bolts and nuts. Do not use other sizes than those described. Check the quality
of the material. The grade A2, for example, is shown on the bolt head for metrics. Do not use
bolts and nuts of a quality inferior to those described.

! CAUTION
Fasteners (bolts, nuts, coupling pins, etc.) that do not have the required strength may fail during
installation, commissioning, or operation and cause serious damage or injury.
• Use only the fasteners supplied with the circuit switcher.

5.3.6 Connecting the High Voltage Terminals

High voltage terminals are optional accessories (supplied when requested by the customer) included
with circuit switchers (Chapter 4, Crate 1, Bag H1 if ordered). If provided by AREVA, attach the optional
HV terminal clamps (or adapters) with suitable hardware to the four-hole pad on the top of the bushings
(Figure 5-9).
1. Verify alignment of the high voltage terminal pads prior to assembly.
2. Before making the connection, thoroughly clean the bare aluminum, bronze or copper contact
surfaces using a wire brush or pad (for example, Scotchbrite®) to remove oxidation.

IMPORTANT
Aluminum oxidizes quickly; it is imperative you complete the preceding step even if the surface looks
clean.

3. Clean tin or silver plated contact surfaces with care to ensure that the surface of the plating is
not broken. Alternatively, you can clean the plated surfaces with a solvent that will not damage
the plating.
4. Immediately apply a thin layer of contact grease such as Penetrox A to all contact surfaces to
prevent further oxidation of the contact surfaces. Brush contact grease onto contact surfaces
with a wire brush or pad.
5. Apply a thin layer of anti-seize compound to the threaded surfaces of fasteners prior to
assembly (Chapter 4, Crate 1, Bag H2 if ordered).
6. Place a washer under the bolt and another under the nut.
7. Fasten the high voltage terminal pads with the accompanying bolts and tighten them to a
torque.
8. Torque the fasteners according to Attachment B within 5 minutes of completing grease
application.
9. Remove excess contact grease leaving a small bead around the outside edge of the joint to
prevent water infiltration.
10. Clean any dirt or debris, which the preparation of the HV terminals creates, from the bushings.

5.4 Checking the SF6 Gas System for Tightness

The switcher has been leak tested at the factory and determined to have a leak rate less than 1% per
year.

5.4.1 Leak Detection Procedure

In order to detect transport damage to the gas system, check the gas pressure [approximately 2.9 to
7.3 psig (0.2 to 0.5 bar)].
• Press the poppet into the DILO fill valve. If no pressure is detected, connect an SF6 bottle to the
fill valve and pressurize to approximately 5 to 10 psi (0.15 to 0.3 bar).
• Test all fittings and flanges for leaks with a suitable halogen leak detector and/or soap solution.

5.4.2 Procedures if a Leak is Detected

• Contact AREVA Inc.‘s Service Department for instructions and or replacement parts.
• Check tightness of all fittings. Re-tighten loose fittings. Replace defective parts.
• Evacuate the switcher to <0.5 mm Hg and hold vacuum for minimum of 4 hours. (See Section
5.4.3)
• Fill per instructions in Section 5.5.
• Perform a leak check test to ensure leaks have been repaired.

! CAUTION
ALWAYS use a pressure-regulating device when filling the switcher. Refer to safety precautions in
Chapter 2 for proper SF6 handling.

IMPORTANT
The SF6 density monitor (Figure 5-10) is a temperature compensated pressure gauge, that is, the
ambient temperature is already considered.

5.4.3 Vacuum Evacuation Procedure

If there has been a leak or you disconnected the piping, pull vacuum on the entire switcher. The
purpose of evacuating is:
• To remove air
• To remove moisture
• To detect leakage
Removing moisture, which adheres to internal surfaces, requires maintaining a vacuum with the pump
running for a long time. Minimizing ambient air entry minimizes drying time.
1. Connect the vacuum pump to the fill port – DILO DN8.
2. Pull a vacuum to less than 0.5 mm Hg for a minimum of 2 hours.
3. Seal the port and turn off the vacuum pump.
4. Wait 30 minutes and watch the vacuum gauge. If the vacuum level rises to greater than 1.0 mm
Hg in 30 minutes, the switcher may:
a. Still contain moisture, in which case continue the evacuating procedure or
b. May have a leak, in which case check for leaks as instructed above.
5. After pulling vacuum, fill the switcher with SF6 to 0.3 to 0.7 bar (4 to 10 psig) and check for leaks
by using a halogen leak detector. (Refer to Section 5.5 for connection and filling.) If you find a
fitting or connector to be defective, perform necessary repairs or replace it.

! CAUTION
ALWAYS use a pressure-regulating device when filling the switcher. Refer to the safety precautions in
Chapter 2 for proper SF6 handling.

IMPORTANT
Never move a switcher with more than 0.3 to 0.7 bar (4 to 10 psig) SF6 pressure.
Never store switchers with a vacuum.

IMPORTANT
For long-term storage, switchers should have 0.3 to 0.7 bar (4 to 10 psig) SF6.
Do not fill the switcher until it is installed on a permanent foundation and all high voltage connections
are made.
Some discoloration may occur to metal surfaces when using a liquid detergent, like dishwashing
liquid, for a leak test. Wash away all soap residues with clean water.

5.5 Filling the Circuit Switcher with SF6 Gas

! DANGER
Improper transport or handling can result in damage to the pole columns. If this is the case, pole
columns may burst when they are being filled to rated pressure.
• To avoid serious accidents, carry out a visual inspection for damage before filling the switcher.
• While filling the switcher with SF6, all personnel must be in a protected location or at a
sufficient distance from the equipment.

IMPORTANT
The nameplate indicates the rated pressure. If the nameplate is missing, the marking on the density
monitor (black dot at the end of the green field on the dial) indicates the rated pressure.
• If there is any doubt about SF6 quality (when using unsealed SF6 cylinders, for example),
check the dew point of the SF6 gas after the filling operation, as described in Chapter 6.
• The density monitor can be checked against the pressure curve in Chapter 1 by using a test
manometer and a thermometer.

NOTE
If the piping has been opened or a pole coplumn has been dissasembled, a vacuum must be pulled on
the entire switcher prior to filling the switcher with gas, per Section 5.4.3.

Carefully follow all safety precautions. Refer to Chapter 2 of this manual for health risks associated with
SF6. For proper SF6 handling, use a gas handling and reclaiming cart. If a handling unit is unavailable,
always use an SF6 gas regulator when filling from the cylinder. Use only SF6 gas filling equipment that
has not been exposed to contaminating moisture, or SF6 by-products.
The SF6 gas density monitor (Figure 5-10) is a temperature compensated pressure gauge, that is, the
ambient temperature is already considered in the measurement. Due to the temperature compensating
mechanism of the gauge, the density monitor will not respond to normal changes in gas pressure due
to temperature fluctuations, and will only respond to changes in density of the SF6 gas system.
The switcher has been leak tested at the factory and determined to have a leak rate of less than 1% per
year.
1. Connect the filling hose to the gas-filling device (SF6 gas cylinder with pressure reducing
regulator or SF6 gas cart).
2. Evacuate the fill hose of all air.
3. If filling from a cylinder, flush the filling hose with a minimal amount of SF6 gas to displace the air
in the hose. Ensure that the hose is moisture-free and that there are no particles, dirt or oil
inside the hose or any fittings.
4. Connect the fill hose to the SF6 fill port (DILO DN8) on the circuit switcher. Refer to Figure 5-11
for the location of the filling port on the circuit switcher.
5. Fill up to the rated density, which the black dot at the upper limit of the green segment of the
density monitor indicates.

GL09-IM INSTRUCTION MANUAL

December 11, 2006
Chapter 5, Page 19
 Assembly, Installation, & Commissioning
for Type GL309 Circuit Switchers

IMPORTANT
In order to be able to fill all of the switchers with the amount of SF6 gas supplied, start filling with the
gas cylinder that contains the least amount of gas. After using it completely, fill with the next emptiest
cylinder, etc. If you do not follow this procedure, the amount of gas supplied will not be enough.

! CAUTION
DO NOT invert the gas cylinder because this will fill the switcher with liquid SF6. The resulting over-
pressurization may burst the pressure relief device.

IMPORTANT
To prevent freezing of the gas cylinder or the filling equipment during SF6 charging, set the charging
pressure to no more than 1 to 2 psig (0.1 to 0.2 bar) above the nominal fill pressure of the switcher,
94.1 psig (6.5 bar).

6. After a temperature equalization period of approximately one hour, check again and correct the
SF6 pressure if necessary. After filling the switcher, remove the hose and replace the fill port
cap.
Three colored areas divide the dial of the WIKA gas density monitor: Green, Yellow and Red. The
position of the needle indicates the SF6 gas density at any ambient temperature.

5.6 Grounding the Circuit Switchers and Enclosures

AREVA GL309 circuit switchers are equipped with ground provisions on the support structure and a
ground bar protruding through control mechanism enclosures consistent with ANSI, NEMA, and IEC
regulations.
Connect the ground cable to the support structure using the NEMA 2-hole ground pad on the lower legs
of the circuit switcher frame.

INSTRUCTION MANUAL GL09-IM

December 11, 2006
Chapter 5, Page 20
AREVA T&D Circuit Switchers Chapter 5 Rev. 1
Type GL309 Assembly, Installation, & Commissioning

If not completed at the factory, install the copper ground bar in the control cabinet using the hardware
supplied so that it protrudes through the bottom of the cabinet.

NOTE
Some orders may request additional grounding points on the exterior of the auxiliary controls cabinet
and the mechanism cabinet. Check these cabinets for stickers that point out additional grounding
locations. If there is a sticker on the mechaism cabinet, there should be one on the auxlilary cabinet.
Connect the two cabinets at the points indicated by the stickers.

Connect a ground cable to the control cabinet ground bar to ensure a proper ground for the control
cabinet and the associated control circuits.

5.7 Manually Charging the Spring Mechanism

Perform the initial spring charging operation of the mechanism manually to reveal any binding
problems. Refer to the exploded view of mechanism in Chapter 8.
• Remove the manual charging handle from its mounting clips on the control cabinet door and
place it onto the charging post of the mechanism.
• Charge the mechanism by turning the handle clockwise [  ] until the spring charge indicator
moves to the "Charged" position.

5.8 Operating the Switcher

IMPORTANT
Refer to Chapter 8 for additional information on spring-operated mechanisms.

! CAUTION
When operating the switcher manually, make sure that:
• Gas pressure is greater than the Lockout set point.
• All tools are removed and personnel are clear of the operating mechanism.
• Control power is removed.
• Only use the manual charge handle when all local control power has been de-energized.
• Do not operate the Manual control switch unless all of the above are observed

! CAUTION
Operating the system with less than the acceptable indicated gas pressure may damage the
interrupter parts. Observe the warning tag below, which is attached to the mechanism.

WARNING
Hazardous: Moving parts inside. No maintenance or other work should
be performed until all electrical power has been removed from the system.
Read the applicable sections of the instruction book, particularly the
section on "safety".

1. Check that the control voltage and auxiliary voltage.

GL09-IM INSTRUCTION MANUAL

for Type GL309 Circuit Switchers

2. Operate the switcher remotely to ensure that the control circuits, motor circuit, and alarms are
functional.
3. You can check low SF6 alarms and lockout settings by slowly bleeding the pressure by means of
the three-way valve (optional) at the gas system manifold block. If a three-way valve is not
provided, follow the procedure below to simulate a gas leak.

! CAUTION
If the control scheme calls for the switcher to open and lockout at low pressure, the switcher will open.

4. In order to simulate a leak in the piping system follow these steps:

• De-couple the three quick-connect valves (Figure 5-12). Loosen the fitting using a wrench, hold
the section of the valve attached to the tank in place using a wrench, to prevent turning. (Refer
to Figure 5-12 for details of the quick-connect valves).
• Slightly push the poppet of the fill port (Figure 5-11) to release the SF6 gas.
• Continue slowly decreasing SF6 pressure until first the alarm value and then the lockout value
are reached.
• Reconnect the three poles with the quick-connect valves. Retighten fittings.
• Fill the system with SF6 gas up to the rated density.

5.9 Checking the Anti-Condensation Heater

• Measure the resistance of the anti-condensation heater at the terminals in the mechanism.
• Check the measured value against the reference value on the routine test report (Chapter 7).

5.10 Wiring the Supply Voltages

! DANGER
Before installing the supply and control cables, make sure the circuit switcher is not energized.

! CAUTION
As soon as you apply the supply voltage and you turn on the motor protection switch, the motor will
charge the closing spring.
• Before applying voltage or turning on the motor protection switch, make sure there are no
objects or parts of the body in the charging system area.
When you apply supply voltage, the anti-condensation heater will be hot. It can burn skin or clothing.
• Do not touch the heater.

Insert all supply and control cables through cable glands and connect them to the terminals in
accordance with the schematic diagram in Chapter 7.

5.11 Optional Installation Procedures

The factory performed the following procedures and tests in the factory and do not need to be redone.
These procedures and tests have no bearing on warranty claims. Please consult your company policy
for the necessity of the following sections.

5.11.1 Checking the Circuit Switcher System Pressure

Check the SF6 gas pressure 6 hours after charging the switcher.

IMPORTANT
Take these readings early in the morning, to avoid inaccuracies caused by solar heating of the circuit
switcher during the day.

• Take a temperature reading of the pole tank to get a close estimation of the SF6 gas
temperature.
• Attach a calibrated pressure gauge to the fill port of the circuit switcher.
• Consult the rated pressure curve in Chapter 1, to find the proper pressure at the recorded
temperature.

5.11.2 Density Monitor Switch Settings

• Connect the density meter and external SF6 pressure source to the fill port on the gas system,
See Figure 5-11.
• Slowly pressurize the system, bringing the density meter to the black dot. Note the pressure and
temperature, and compare readings with chart values shown at the end of Chapter 1.

GL09-IM INSTRUCTION MANUAL

December 11, 2006
Chapter 5, Page 23
 Assembly, Installation, & Commissioning
for Type GL309 Circuit Switchers

• Reduce pressure slowly to ensure that contacts operate at the proper alarm and lockout values.
• See switcher specific drawings for accurate densities (refer to Chapter 7).
• The contacts of the WIKA density meter are not adjustable. If you find that the density meter is
out of calibration, notify AREVA T&D Inc.

5.11.3 Checking the Closing Spring Charging Time

As soon as the operating mechanism is energized, the motor starts to charge the closing spring. When
fully charged, the motor limit switch automatically turns off the motor supply. The spring charge
indicator moves to the "Charged" position.
• Measure the motor charging time after a closing operation
• Check the measured charging time against the reference values in the routine test report
enclosed in Chapter 7.

5.11.4 Timing Tests

! CAUTION
Never operate the switcher with an SF6 gas density below the lockout value.

Before beginning test operations make sure that:

• The circuit switcher is filled to its rated density.
• The closing spring indicator shows "Charged.”
• The supply voltage is at its rated value.
• All linkages are connected.
Perform the operations using a circuit breaker analyzer to measure the contact operating times of the
circuit switcher. The values must correspond to those given in the routine test report in Chapter 7.

NOTE
The closing time is the time from energizing the close coil to contact touch.
The opening time is the time from energizing the trip coil to contact separation.

5.11.5 Measuring Contact Resistance

Measure the resistance of the main current path with the switcher closed using an instrument with a
minimum current of 100 A DC. Connect directly to the upper and lower terminal pads. Ensure good
electrical contact by cleaning an area for test equipment connection. Compare recorded measurement
with those in the factory test report (refer to Chapter 7). The maximum resistance between HV-terminal
pads should not exceed 62 µΩ (including terminal pad resistances) for up to 2000 A.
The measured contact resistance value may be slightly higher if there are additional connectors,
elements, or terminals added to the circuit. If this is the case, consider the resistance of those items.

5.11.6 Checking the Manual Operating Function

Check the manual operating function of the mechanism. Perform one closing and one opening
operation by turning the respective manual operating lever.

INSTRUCTION MANUAL GL09-IM

December 11, 2006
Chapter 5, Page 24
AREVA T&D Circuit Switchers Chapter 5 Rev. 1
Type GL309 Assembly, Installation, & Commissioning

5.11.7 Checking the Anti-Pumping Circuit

When an electrical closing command and an opening command are applied simultaneously and held
on, the circuit switcher will always reach the open position.
• To check operation of the anti-pumping system, first move the switcher to the open position.
• While continuously applying an opening command, give also a closing command.
If the circuit switcher is operating properly, it will execute only one closing operation and one opening
operation.
• For the next testing step, put the switcher in the closed position.
• While continuously applying a closing command, give also an opening command.
• If the circuit switcher is operating properly, it will execute only one opening operation.
The anti-pumping system is automatically reset when there are no more operating commands.

5.11.8 Checking the Lockout Function

Short-circuit the contacts of the SF6 density monitor. Verify that the circuit switcher cannot be operated
by electrical closing and opening commands.
• Jumper the density monitor contacts at the terminal strip.
• Give one closing command and one opening command.
If the circuit switcher is operating properly, it will not execute any operation.
• Remove the jumpers from the terminal strip.

5.12 Commissioning Checklist

The commissioning checklist’s primary purpose is to ensure that in the course of commissioning, all of
the important work, which must be carried out to guarantee the reliability of the switcher, is performed.

IMPORTANT
In the event of any warranty claim, the absence of this checklist may result in reduction of the claim.

Please note:
1. General information such as name of the user, name of substation, type of switcher, serial
number and the year of manufacture must always be filled in.
2. Each commissioning checklist is only valid for one switcher. Treat the Commissioning form in the
manual as a master and photocopy it whenever commissioning or recommissioning the switcher.
3. Note the serial number of the switcher on each page.
4. Carry out all work described in previous sections and initial the corresponding sections of the
checklist.
5. After completing the commissioning process, the commissioning engineer must sign and date the
commissioning checklist.

1.0 Function of 3-way valve

3-way valves are optionally provided as part of the gas system to enable the
customer to test and verify the alarm and lock-out points of the gas monitoring
device. The 3-way valve provides isolation from the interrupting chamber gas
system for testing or replacement of the gas monitoring device.

2.0 Device description

The 3-way valve is a ball valve that has a center-off orientation. The 3-way ball
valve is coupled with a mud dauber. The mud dauber acts as a vent and has a
screen to prevent insect from entering the valve. A normal-test nametag (See figure
1) is mounted with the 3-way valve to display the position of operation. The
orientation of the valve handle (with respect to the tag) depicts the corresponding
flow of the gas system.

Fig 1: Example device tag

Due to gas system variations from differences in breaker or switcher design, the 3-
way valve may be oriented differently. Refer to the nametag associated with the 3-
way valve on your equipment for proper handle orientation.

3.0 Device operation

3.1 Normal position

When the handle on the 3-way valve is turned to the normal operating
position (refer to fig 2), the gas flow in the system interrupting chamber is
permitted to flow unrestricted to the gas density monitoring system.

Fig 2: Valve in normal position

3.2 Center-off position

When the handle of the 3-way valve is rotated 90 degrees from the normal
position (refer to fig 3), the gas density monitor is isolated from the gas
system.

Part I, Page 5 INSTRUCTION MANUAL-ADDENDUM Rev 0 (03/28)

3.3 Test position

When the handle of the 3-way valve is turned beyond the center-off position
(refer to fig 4), the density monitor can be evacuated (reduction of pressure)
of gas to alarm and lockout points for testing and verification of proper
function.

Fig 4: Valve in test position

SF6 should never intentionally be released into the atmosphere.

Please refer to the appropriate sections in the equipment instruction manual on SF6 gas
for hazards and environmental impacts.

4.0 Procedure

• Rotate handle of 3-way valve 90 degrees to center-off position to isolate gas

density monitor from gas system.
• Remove mud dauber from 3-way valve and attach a SF6 gas reclaiming cart to
the valve. Every attempt must be made to avoid releasing SF6 into the
atmosphere.
• Slowly rotate the valve handle to begin depressurization of gas in volume of
density monitor to test alarm and lock-out points (refer to the nameplate on your
equipment for the alarm and lock-out values of your density monitor).
• Return valve handle to the center-off position.
MULT-IM ALSTOM T&D INC.
Part I, Page 6 INSTRUCTION MANUAL-ADDENDUM Rev 0 (03/28)

• After testing is completed, remove reclamation cart and reinstall mud dauber to
3-way valve.
• Rotate the valve handle back to the normal position.

WARNING
Make certain to return handle of 3-way valve to normal position prior to putting
equipment into operation. Failure to do this will prevent the gas monitoring system
from operating correctly, and may result in improper equipment function or failure.

Be sure not to completely evacuate gas from the system. It is imperative that the
internal pressure is greater than ambient, so that moisture is unable to enter the
gas system of the equipment.

WARNING
SF6 possesses powerful greenhouse gas characteristics. It possesses a global
warming potential of approximately 24,000 times that of carbon dioxide over a
100-year time horizon, with an atmospheric residency of more than 3,000 years. It
is important for participants to recognize the importance of responsible use and
careful management of SF6 gas.

2. PURPOSE AND SCOPE

This document defines the technical requirements for torque values for externally threaded
mechanical fasteners. These requirements are intended to serve as a general reference for
Areva personnel, as well as customers and suppliers, in the design, fabrication and repair of
Areva T&D Inc. products. This specification is a supplement to the assembly drawings from
which it is referenced and is subordinate to any specific values that are designated on the
respective drawings. The development-engineering department will control this document.

3. DERIVATION, GENERAL REQUIREMENTS

The torque values that are provided in the following table have been calculated to pre-stress
the fastener between 65-80% of tensile yield. A 0.20 (empirical) torque coefficient has been
assumed in the computation of the resulting values. Listed values are nominal. Tolerance is
± 20%.

NOTE: Metric fasteners threaded into cast aluminum shall not exceed torque
values listed for ASTM F 568M Property Class 5.6.

NOTE: Standard fasteners threaded into cast aluminum shall not exceed torque
values listed for SAE Grade 2.

Type GL309 Maintenance and Troubleshooting

6.0 General
These maintenance directives incorporate measures for avoiding the hazards involved in the
application of SF6 gas to switchgear. Such directives are protective measures and recommendations
for the user of SF6 switchgear.
Any personnel performing maintenance or inspection on SF6 switchgear should read this section and
comply with these instructions as well as the safety precautions prescribed by their employer. Failure to
observe the safety precautions described herein, and those defined by the employer, may result in
bodily harm or asphyxiation.

6.1 Recommended Maintenance Schedule

Circuit switchers, using SF6 as a quenching medium, need very little maintenance. The decisive
influencing factors that affect the condition of the circuit switcher are the number of short-circuit
operations, operating frequency, and operating time (hours of operation).

IMPORTANT
In the case of service under extreme conditions, i.e.,
• continuously high ambient temperatures,
• presence of abrasive dust or grit,
• heavy dust accumulation,
• continuously high humidity,
• presence of aggressive gases or vapors,
Shorten the inspection and maintenance intervals.

Under normal service conditions, the maintenance program can be summarized as follows:

6.1.1 Maintenance Walk-by – Class M1 Service

At least once a year, with the circuit switcher operating normally, perform a visual inspection of the
switcher and the operating mechanism. Refer to Section 6.2 for further details.
If the circuit switchers are scarcely used, perform at least 2 C-O duty cycles per year in order to check
that the circuit switcher and associated control circuits are working properly.

6.1.2 Inspections – Class M2 Service

Every 6 years, de-energize the circuit switcher and inspect the switcher pole units, operating
mechanism, and linkage without dismantling the sub-assemblies. Clean the equipment and verify all
connections, gas, and fluid levels are correct. Refer to Section 6.3 for further details.

6.1.3 Overhaul – Class M3 to M5 Service

Circuit switcher repairs depend on the number of operations performed and the value of breaking
currents. AREVA T&D recommends opening the circuit switcher and repairing contacts depending on
the following guidelines: (Refer to Sections 6.4 to 6.6 for details)
• Length of time in service exceeds 12 years. [Class M3 Maintenance]
• Length of time in service exceeds 24 years. [Class M4 Maintenance]
• Electrical wear, when the accumulated fault current interrupted exceeds that shown in the
following Figure 6-1. With certain exceptions, the electrical wear limit (2500 operations) is not

GL09-IM INSTRUCTION MANUAL

January 2, 2007
Chapter 6, Page 5
 Maintenance and Troubleshooting
for Type GL309 Circuit Switchers

reached before 24 years of operations. However, if the switcher does reach it, it is necessary to
replace the breaking elements, Contact AREVA T&D customer Service for assistance. [Class
M5 Maintenance]

IMPORTANT
The time intervals given above are based on empirical values determined over many years of field
experience. Regionally applicable standards and regulations may specify shorter intervals.

Perform switcher overhaul maintenance as soon as any one of the above events occurs. Inspect the
circuit switcher used most often and then, depending on the results observed, adapt the maintenance
program for the other switchers.

INSTRUCTION MANUAL GL09-IM

January 2, 2007
Chapter 6, Page 6
AREVA T&D Circuit Switchers Chapter 6 Rev. 1
Type GL309 Maintenance and Troubleshooting

Follow the relevant safety precautions. Dismantling the circuit switcher poles is not necessary for the
following recommended inspections.
• Visually inspect for damage, especially to bushings.
• Check for corrosion or damage to metal parts and piping. Especially notice the condition of the
bolted flanges.
• Check for clear air vents in the base frame and in the mechanism and controls cabinets.
• Check cable connections.
• Functional check the anti-condensation heaters.
• Check the SF6 density (the SF6 density monitor must indicate in the green sector on the WIKA
gauge).
• Check the SF6 gas quality.

6.2.1 General Condition of Equipment

Visual inspection of equipment; if patches of corrosion are found, begin reconditioning the affected
parts (matching surface finish and protection). Pay particular attention to parts that are galvanized steel,
painted or not, or are painted aluminum alloy.
Follow the procedures below to recondition the surfaces:

6.2.1.1 Repairing Hot-dipped Galvanized Parts

• Thoroughly brush any oxidized parts,
• Thoroughly degrease the area with a solvent,
• Apply a coat of zinc paint.

6.2.1.2 Repairing Painted Parts:

a. With light scratches:
• Thoroughly degrease the area with a solvent,
• Apply a coat of polyurethane lacquer, using a brush.
b. With deep scratches or flaking:
• Scour the surface with A400 emery paper until clean and smooth,
• Thoroughly degrease the area with a solvent,
• Apply a coat of primer and allow it to dry for 24 hours,
• Apply a coat of polyurethane lacquer, using a brush.

6.2.2 SF 6 Gas Pressure and Quality

Check the SF6 density (the SF6 density monitor must indicate in the green sector on the WIKA gauge).
If the density monitor indicator is in the yellow or red area, fill up the switcher with SF6.

! CAUTION
Chapter 5 describes in detail the procedure for filling the circuit switcher with SF6.

Check the SF6 gas quality with respect to the moisture content, SF6 content, and acidity. Reference
values are:

GL09-IM INSTRUCTION MANUAL

Dew point: < -10°C at nominal pressure.
SF6 content: > 98%
Acidity: ≤10 ppm
Moisture Content ≤ 500 ppm

6.2.3 Air Vents and Anti-Condensation Heater Operation

Air vents should be clean, free of dust, and unobstructed. If necessary, clean using a solvent. Make
sure that the permanent resistors are working properly by checking that these give off heat and that
there are no overheating marks (a zone notorious for this).
Check the function of the anti-condensation heaters: Turn the heaters on and allow time for them to
heat up. Verify the heaters have gotten warm and then shut them off.
For thermally controlled heaters (if applicable), verify that the heaters turn on and off at the preset
temperatures. If necessary, change heaters found to be defective.

6.2.4 Operation Counter

Read the counter(s) and note these figures on the maintenance inspection card. The number of circuit
switcher operations recorded influences future maintenance operations.

6.2.5 Functional Check of the Electrical Control Circuits

Perform at least two Open-Close duty cycles per year in order to check that the circuit switchers and
associated control circuits are working properly; especially if the circuit switchers are seldom used.

6.3 M2 Service – 6 Year Inspections

! DANGER
Follow all regional and operator-specified safety precautions. In addition, observe the following
instructions:
• Isolate the switcher.
• Closing spring position indicator must show "spring discharged."
• Ground the switcher.
• Disconnect the supply and motor voltages. (Voltages are required for the procedures
described in 6.2.2 and 6.2.5.)

Every six years, de-energize the circuit switcher and inspect the switcher pole units and operating
mechanism without dismantling either the sub-assemblies or the interrupting chambers. Clean the
equipment and verify all connections, gas, and fluid levels are correct. Maintenance is to be performed
only by trained personnel or AREVA service technicians. It is not necessary to dismantle the switcher
pole for the following maintenance:
1. Take the circuit switcher out of service.
2. Perform all inspection items described in Section 6.2 preceding.
3. Check the terminal connections inside the control mechanism and the spring mechanism
enclosures.
4. Check the linkage bolts torques.

INSTRUCTION MANUAL GL09-IM

January 2, 2007
Chapter 6, Page 8
AREVA T&D Circuit Switchers Chapter 6 Rev. 1
Type GL309 Maintenance and Troubleshooting

5. Check the bolted connections for proper torque.

6. Check the terminal connections on the HV terminals.
7. Functionally check the electrical control circuits.
8. Measure the operating times.
9. Measure the resistance of the main current path.

6.3.1 Tightening High Voltage Terminals

With the electric cubicle out of service, check that all electrical connections are tightened correctly and
check the torque on panel mounting hardware.

6.3.2 SF 6 Density Monitor Set Points

Check the SF6 density monitor set points by following procedures in Chapter 5. If you find the values
are outside required tolerances replace the density meter.

6.3.3 Tightening Mounting Hardware

Use a torque wrench to check and adjust the tightness of screws on sub-assemblies not subjected to oil
or gas pressure. Check for the correct torque on all accessible bolt connections. Refer to Attachment B
for acceptable torque values.

NOTE
Always lubricate the threads to prevent galling.

6.3.4 Relay Operation

Check relay operation by executing the following circuit switcher sequences:
• closing lock-out
• automatic opening
• anti-pumping
Check that the following signals are working:
• SF6 pressure decrease

6.3.5 Resistance Measurement

Measure the resistance directly at the HV terminals with the circuit switcher closed and a minimum of
100 A DC. Ensure good electrical contact of the test leads. The values have to correspond to those
given in the routine test certificate of the specific switcher. The maximum resistance between HV
bushing terminal pads should not have increased more than 10 µΩ of the first value recorded at
commissioning.

6.3.6 Bushing Insulators

Check the condition of the bushing insulators to assure that they are free from impact marks,
splintering, cracks, dust deposits, pollution etc. If you discover any dirt or dust, clean with a dry rag. If
you find any abnormalities, contact AREVA T&D Customer Service, in order to change the defective
parts.

GL09-IM INSTRUCTION MANUAL

January 2, 2007
Chapter 6, Page 9
 Maintenance and Troubleshooting
for Type GL309 Circuit Switchers

6.3.7 Measuring Operating Times for Poles and Auxiliary Contacts

Measure the operating times of the poles and auxiliary contacts. Perform operations using a circuit
breaker analyzer to measure the contact operating times of the circuit switcher. Ensure the values
correspond to those given in the routine test reports. If the values measured are outside the routine test
reports, contact AREVA T&D Customer Service.

NOTE
The opening time is the time from energizing the trip coil to separation of the main contacts.
The closing time is the time from energizing the close coil to contact touch.

6.4 M3 Service – 12 Year Overhaul

Perform switcher overhaul maintenance as soon as the length of time in service exceeds 12 years.
Inspect the circuit switcher used most often and then, depending on the results observed, adapts the
maintenance program for the other switchers.
Take the circuit switcher out of service, and open the switcher pole units as necessary. Reconditioning
usually refers to replacement of interrupter wear parts. Overhaul or reconditioning is to be performed
only by trained personnel or AREVA service technicians.

! CAUTION
NEVER use Molykote lubricants on any internal areas in contact with SF6.

• Coat all flanges and areas exposed to water with Dow 111 silicone grease to prevent moisture
penetration and to lubricate the O-rings and O-ring grooves. Apply lubricants or grease by hand.
• Do not use brushes or any device for applying lubricants because they may introduce particles
during lubrication. While applying lubricants by hand, if you feel any particles, thoroughly clean
the areas and reapply the proper lubricants or grease. Take care lubricating gaskets, seals, etc.;
verify that there is no damage and that no particles are present that would prevent a gas tight
seal.
• Clean all functional elements with a lint free wiper that has been soaked in denatured alcohol.
Grease the parts according to the greasing instructions. Replace parts when necessary.
• If you removed bolted connections during work, reinstall all hardware. Replace damaged
hardware if there is any visual damage.
• Replace the absorption filter (desiccant), refer to Section 6.6.4.6, whenever a pole unit has been
opened to the environment for long periods or if it is contaminated with SF6 decomposition by-
products. Do not remove the replacement absorption filter (desiccant) from its protective
container or install it until the switcher pole unit is completely assembled and ready for pulling
vacuum.

6.4.1 Discharging the Closing Spring

AREVA recommends discharging the closing and tripping springs when carrying out maintenance work
on the circuit switcher for reasons of personal safety. If the following conditions are true:
• The circuit switcher is in closed position.
• The closing spring is charged.
Then proceed as follows:
1. Interrupt the motor supply voltage;

INSTRUCTION MANUAL GL09-IM

January 2, 2007
Chapter 6, Page 10
AREVA T&D Circuit Switchers Chapter 6 Rev. 1
Type GL309 Maintenance and Troubleshooting

2. Carry out one opening operation;

3. Carry out one closing operation;
4. Carry out one opening operation.
The closing and tripping springs are then discharged so that no more operations are possible.

6.5 M4 Service – 24 Year Overhaul

Perform switcher overhaul maintenance as soon as the switcher reaches 24 years of service. Inspect
the pole or circuit switcher used most often and then, depending on the results observed, adapt the
maintenance program for the other switchers.

6.6 M5 Service – Electrical Wear Overhaul

Circuit switcher repairs depend on the number of operations performed and the value of breaking
currents. This is called the “electrical wear.” AREVA T&D recommends opening the circuit switcher and
repairing the contacts when the accumulated fault current interrupted exceeds that shown in Figure 6-1.
With certain exceptions, the electrical wear limit is not reached before 24 years of operations. However,
if the switcher reaches it, then it is necessary to inspect and repair the breaking elements, Contact
AREVA T&D customer Service for assistance.

6.6.1 Electrical Wear Limits – Permissible Number of C-O Operations

Arcing contact replacement is necessary if the GL309 reaches a total number of interruptions defined
for each current level by the graph in Figure 6-1.
The curve can be estimated by the following equation:

N = 7598.3 ⋅ I −1.9282 for 2 kA < I < 31.5 kA

Each pole unit of the GL309 has a cumulative electrical endurance of at least 55 kA2·s. This value is
based on the following equation:

Type GL309 Maintenance and Troubleshooting

6.7 Recommissioning a Reconditioned Circuit Switcher

Following re-assembly, perform checks according to the commissioning checklist in Chapter 5. In
addition:
• Check the resistance across the terminals (refer to Section 6.3.5).
• Ensure the integrity of the insulation by a Megger test.

6.8 Troubleshooting
Before beginning any troubleshooting, disconnect the switcher from the high voltage system and
ground it in accordance with the applicable company safety regulations.

6.8.1 Control System

In the event of a failure of electrical commands or if the commands are delayed, proceed as follows:
1. Check the position of the closing spring.
2. Measure the supply voltage.
3. Disconnect the control circuits.
4. Check the SF6 gas density.
5. Check that the terminal connections are tight and correct.
6. Check the wiring against the diagrams. Correct, if necessary.
7. Check the trip and close coils, and replace any defective coils.
8. Check the reason for and eliminate any mechanical jamming.
9. Check the contactors in the defective circuit. Replace if necessary.
10. The density monitor may read correctly but the switches may be malfunctioning. If the SF6
density monitor is defective, replace it.
11. Switch on the supply voltage.

6.8.2 SF 6 Gas System

In the event of an "SF6 alarm,” check the gas pressure and refill. Check the density monitor and, if
necessary, replace it.
If you suspect gas leakage, check all flange connections as well as all pipe and welded fittings with a
leak detector, leak detection spray, or soap.
Renew faulty welded connections and tighten leaking connections. In case of leaking flanges,
disassembly of the respective switcher pole may be necessary.

6.10 Spare Parts and Service Policy

Thanks to the advanced technology used in the manufacturing of AREVA gas circuit switchers, a very
limited amount of spare parts and service is required during the normal life of the equipment.
Due to the large number of parts in any given device that are especially for gas switcher requirements,
it is recommended that replacement parts be purchased from AREVA.
When ordering replacement or renewal parts, contact AREVA, and have the switcher serial number
available for information. The switcher nameplate, which mounts on the outside of the control cabinet
door, shows the serial number. Also furnish a complete description of each part as outlined, the

INSTRUCTION MANUAL GL09-IM

Chapter 6, Page 30
AREVA T&D Circuit Switchers Chapter 6 Rev. 1
Type GL309 Maintenance and Troubleshooting

quantity required and, if possible, the number of the purchase order on which the switcher was
originally furnished.
All spare parts should be stored in a clean, dry location and out of the sunlight for maximum life
expectancy.
Depending on the geographical location of the equipment, a Service Contract may be available from
AREVA. For more information, contact your local AREVA representative.

Type GL309 Additional Operating Mechanism Instructions

8.1 Spring Operating Mechanism

The operating mechanism consists of a self-supporting steel structure. For storing the required
operating energy, helical compression springs are charged by an electric motor via a gear unit (Figure
8-1). Electrical actuation of the closing and opening coils causes latches to be unlatched, which
releases the energy of the springs for operating purposes. The spring energy transmits to the pole
columns by the lever on the rear of the operating mechanism, the drive rod, and the connecting rods.

8.1.1 Charging the Closing Energy Storage Mechanism

Numbers in parentheses ( ) refer to items in Figure 8-1.
After applying the control voltage, the motor (70.01) immediately starts up and charges the closing
spring (70.25) via the gear unit (70.04), crank wheel (70.30), and chain (70.26). This operation stops
once the crank pin (70.29) with linked chain (70.26) has gone beyond top dead center and supports the
roller (70.28) of the crank wheel (70.30) on the closing latch (70.05).
At the conclusion of the charging process, the tooth space (70.27) of the crank wheel (70.30) has
reached the driving pinion. This allows the gear unit (70.04) and the motor (70.01), which the control
cam (70.22) and the motor limit switch (70.24) turns off, to run down and stop unimpeded without
loading the closing latch (70.05).
The repositioned motor limit switch (70.24) has closed the closing circuit, and the spring position
indicator (70.31) has been switched to "closing spring charged."

8.1.2 Closing Operation

Numbers in parentheses ( ) refer to items in Figure 8-1.
The closing latch (70.05) releases by electrical command to the closing coil (70.06) or by operation of
the manual release mechanism (70.07). The closing shaft (70.09) is accelerated by action of the closing
spring (70.25) linked to the crank wheel (70.30).
The cam disc (70.10) turns the adjacent roller follower (70.11) in the closing direction. The circuit
switcher is closed by means of the main shaft (70.12), the drive lever (70.18), and a coupled linkage. At
the completion of the closing motion, after rotating 60°, the main shaft (70.12) lowers onto the opening
latch (70.16) safely and with low impact by a lever arm of the roller follower (70.11), thanks to the
especially designed cam disc (70.10). At the same time, the cam disc (70.10) has left the roller follower
(70.11), and the circuit switcher is locked in the “Closed” position and can now be opened.
In the course of the closing motion, the opening springs (70.20 and 1.806) are charged. The excess
residual energy is stored again in the closing spring.
Control, indicating, and latching functions at the end of the closing motion:
1. The auxiliary switch (70.21) coupled to the main shaft (70.12) has closed the opening coil circuit
and interrupted the closing circuit. The circuit switcher can open electrically, but another closing
operation or a pulse applied to the closing coil is prevented.
2. A lever (not shown) that is controlled by the main shaft (70.12) has blocked the closing latch
(70.05) and thus mechanically prevents another closing operation.
3. The position indicator (70.52) has been turned by the main shaft (70.12) to the closed position.
4. The motor limit switch (70.24) actuated by the control cam has closed the motor circuit.
5. The closing coil circuit has been interrupted by a contact of the motor limit switch (70.24). This
prevents another electrical closing operation.

for Type GL309 Circuit Switchers

6. At the same time, the spring position indicator (70.31) has been set to "closing spring
discharged."

8.1.3 Recharging the Closing Energy Storage Mechanism

Numbers in parentheses ( ) refer to items in Figure 8-1.
When the control cam (70.22) at the end of the closing motion moves the motor limit switch (70.24), the
motor circuit is closed, and the closing spring (70.25) is automatically re-charged.

8.1.4 Opening Operation

Numbers in parentheses ( ) refer to items in Figure 8-1.
The opening latch (70.16) releases by the electrical command to the opening coil (70.15) or by
operation of the manual release mechanism (70.13). The action of the charged opening springs (70.20
and 1.8.06) causes the main shaft (70.12) and the circuit switcher that connects to it to be accelerated
in the open direction. Towards the end of the opening operation, the opening dashpot (70.17) becomes
active and dampens the moving parts of the circuit switcher and operating mechanism until they come
to a complete stop.
Control, indicating, and latching functions at the end of the opening motion:
1. The auxiliary switch (70.21) coupled to the main shaft (70.12) has interrupted the opening coil
circuit and closed the closing circuit. This prevents another electrical opening operation. An
electrical closing operation is again possible
2. A lever (not shown), that by the main shaft (70.12) controls, has again released the closing latch
(70.05) for a subsequent closing operation. The circuit switcher can be closed mechanically.
3. The position indicator (70.52) has been turned to the “OPEN” position by the main shaft.

4. The closing spring is fully charged when the spring charge indicator moves to the “Springs
Charged” position.

8.1.7.2 Discharging the Closing Spring

AREVA recommends that for reasons of personal safety, the closing and tripping springs be discharged
when carrying out maintenance work on the circuit switcher. If the following conditions are true:
The circuit switcher is in the closed position,
The closing spring is charged,
Then proceed as follows:
1. Interrupt the motor supply voltage;
2. Carry out one opening operation;
3. Carry out one closing operation;
4. Carry out one opening operation.
The closing and tripping springs are then discharged so that no more operations are possible.
