3 Product Description
3.1 Outdoor Switching Module
The OSM15/25_Al_1 is a three-phase vacuum circuit breaker designed for outdoor application with the rated
maximum voltage of 15.5 kV and 27 kV correspondingly.
The circuit breaker is installed inside of a lightweight aluminum enclosure with a superior corrosion protection
and very heavy pollution areas application rating. The enclosure of the Outdoor Switching Module
encapsulates a magnetic actuator, mechanical trip and lockout mechanism and auxiliary electric circuits that
contain passive electronic components only.
The switching module is equipped with six high voltage bushings with embedded current and voltage sensors.
The bushings are covered by silicone rubber insulation and mount on the top of the tank and provide 500 mm
(OSM15) or 860 mm (OSM25) creepage distance.
The bushings are marked with the terminal designation X1, X2 or X3 for the default source side and X4, X5 or
X6 for the default load side. The source and load side can be reversed in the RC settings if required.

Mechanism Enclosure
The switching module mechanism enclosure is made of a corrosion resistant anodized aluminum alloy. The
enclosure is coated with light gray powder coating.

15
 Fixing holes (M12) on each side of the enclosure allow the application of various mounting kits and installation
on poles and other structures.
The earthing provision (M12) is labelled for identification.

Magnetic Actuator
Tavrida Electric has the most reliable mechanical structure of the vacuum circuit breaker. It uses single-coil
magnetic actuators. All switching elements of a pole are assembled along a single axis. All mechanical
movements are therefore direct and linear. Design of the magnetic actuator guarantee minimum contacts
discrepancy at closing and electrical or mechanical tripping.
Due to the design, any typical failures of critical components, such as mechanical latching, gears, chains,
bearings and levers, tripping and closing coils, motors to charge springs are completely avoided.

Vacuum Interrupter
Tavrida Electric vacuum interrupters are the most compact in its class and show excellent mechanical, voltage
withstand and current breaking capabilities. The use of a specially designed axial magnetic field distribution
provides even current density over the contact surface and consequently substantial improvement of vacuum
interrupting performance. Advanced technology and materials provide vacuum integrity in vacuum interrupter
during the entire switching module lifetime (30 years).

Current and Voltage Sensing

Current sensing is performed by low power current sensors (Rogowski coils) that are inbuilt into each pole. It
ensures a precise acquisition of both phase and neutral currents at a very wide range without saturation.
Six precise low power capacitive voltage sensors on source and load side terminals are inbuilt into poles. It
allows the recloser to provide power quality monitoring and network self-healing algorithms implementation.
For details on sensor parameters refer to “Technical Parameters” section of this guide.

Mechanical Trip and Lockout Mechanism

A mechanical trip hook is located at the bottom of the mechanism enclosure (Figure 3). When the hook is
pulled down, the Outdoor Switching Module is mechanically opened, locked in the OPEN position and
electrically isolated from the driver. The “Coil Isolated” warning event is generated by the RC5_4 to provide
indication of the locked state. The Outdoor Switching Module remains locked and cannot be operated until the
trip hook is pushed back into the operating position.

Figure 4
Mechanical trip hook

Main Contact Position Indicator

The position indicators are located under a protective cover at the bottom of the mechanism enclosure and is
clearly visible from the ground. The indicator color is red “I” when the main contacts are closed and green “O”
when they are open.

16
 Figure 5
Main contact position indicator

3.2 Control Cable

Umbilical_5 control cable connects the Outdoor Switching Module actuator, metering and auxiliary circuits to
the RC5_4. Control cable wires are well protected from UV radiation and sharp objects. The cable is equipped
with a heavy duty 42 pin male connector on the Outdoor Switching Module side and a heavy duty 32 pin female
connector on the Recloser Control side.
Control cable length can be 5, 7, 12 or 20 meters.

Figure 6 Figure 7
Control cable Heavy duty connector

3.3 Recloser Control

The RC5_4 is a new generation control box that is the result of more than 20 years of recloser production and
service experience.
The RC5_4 recloser control cubicle is made from powder coated anodized aluminum alloy.
The RC5_4 has 4 drainage filters installed in the bottom, one per corner. It allows effective Recloser Control
dehumidification without using any heaters. Advanced drainage filters design ensure IP65 for Recloser Control.
Removable customization plate 180x70 mm is placed at the bottom of Recloser Control. It is possible to modify
customization plate and install additional modules or cable glands in case required.

Radial line recloser
The Radial line recloser provides protection against the following faults:
• Short circuit. Phase-to-phase and three-phase short circuits;
• Earth fault. Single-phase and double-phase earth faults;
• Bolted fault. Very low impedance fault, typically caused by human factor or accident;
• Low current earth fault caused by a high impedance phase to ground short circuit;
• Upstream broken conductor. Conductor touching ground at the source side;
• Downstream broken conductor. Conductor touching ground at the load side;
• Low system voltage caused by an incorrect network operation mode, tap changer malfunction, under-
generation, or islanding. This protection prevents sensitive loads, such as motors, from overload and
failure;
• Low system frequency caused by local under-generation, islanding or generation system malfunctions;
• High system voltage caused by tap changer malfunction, over-generation or islanding. This protection
prevents sensitive loads from damage;
• High system frequency caused by islanding.
Protection elements against short circuit, high impedance earth fault, low system voltage, and low system
frequency faults are provided with independent reclosing elements.
Reclosing elements are controlled by the Voltage Reclosing Control (VRC). The VRC blocks autoreclosing if
power quality fails to meet customer requirements.

Ring line recloser

The Ring line recloser is provided with a unique source detector with the source threshold voltage setting. This
source detector continuously detects the direction of power flow through the recloser main contacts. The
source threshold voltage setting provides possibility to define the live line voltage level according to
particularities of the network configuration.
The Ring line recloser provides protection and automation as the radial line recloser. In addition the Ring line
recloser has directional elements to determine power flow direction (direct/reverse). The Ring line recloser has
independently configurable sets of settings for direct and reverse power flow.
In addition Ring line recloser provides the following functionalities involved in loop automation, self-healing
schemes and independent power producers’ connection to the grid:
• Loss of Supply – provides recloser tripping if it detects source lost.
• Automatic Backfeed Restoration – provides automatically closing a normally open recloser if it detects a
source on the either side of the recloser and absence of a source on the other side
• Live Load Blocking – monitors power supply from the load and source side and only allows closing if a
source is present at the correct side;
• Synchronization Check – provides closing command execution only if voltage parameters from both sides
are within predefined ranges.

Rezip recloser
The Rezip recloser is used to automate various networks where traditional time and current grading is
impossible. Unlike a conventional recloser, the Rezip recloser can be used in ring and meshed networks and
self-healing schemes. Any number of Rezip reclosers can be connected in series.

Standard sectionalizer
Standard sectionalizer provides automatic segregation of the faulty segment of the radial or ring feeder basing
on number of upstream recloser operations.
Standard sectionalizer provides detection and subsequent trip during the dead time of upstream recloser
• Short circuit. Phase-to-phase and three-phase short circuits;
• Earth fault. Single-phase and double-phase earth faults;
• Low current Earth fault caused by a high impedance phase to ground short circuit.

29
Rezip sectionalizer
The Rezip sectionalizer provides detection and subsequent trip during dead time of upstream recloser as the
Standard sectionalizer.
In addition Rezip sectionalizer automatically finds and segregates the faulty segment of radial, ring or meshed
feeder by opening all devices which have sensed fault current and then close them one by one till the faulty
segment is found. When faulty segment is found, only the nearest device to the fault will open to lockout.
Rezip sectionalizer can be used with other automation features to provide sophisticated network healing
algorithms.
The Rezip sectionalizer allows to:
• Overcome the limit of the number of sectionalizers in series;
• Minimize protection settings design resources (same protection settings for all Rezip sectionalizers for the
most applications can be programmed);
• Minimize the number of upstream recloser operations and power interruptions for healthy network sections.

Protection Elements
OCR mode
OCR mode defines whether device operates as Recloser with OCR element or as a Sectionalizer with SECR
element.
OCR mode can be independently selected for each protection group.
OCR mode settings are described in Table 15.
Table 15 – OCR mode settings
Settings Range Default
OCR mode Recloser/Sectionalizer Recloser

Source Detector (SD)

The source detector element has two main functions:
• Provides power flow direction to directional protection elements (ring operation mode);
• Provides source side information for loss of supply protection element.
Protection elements: AR OC, HL, AR SEF, VU, CU, AR UV, AR UF, AR OV, AR OF, CCV and ABR operation
depends on the source side being identified. If power flows from „Source +“ side, then „Set +“ protection
settings are active, if power flows from „Source -“ side, then „Set -“ protection settings are active.
Source detector has a changeable voltage detection level. In case power source voltage is less than specified,
it will not consider as a source.

Bolted Fault (BF)

This element provides instantaneous tripping when bolted fault conditions are detected. As it deals both with
positive sequence voltage and current it provides better sensitivity for bolted faults than conventional highset
overcurrent elements.

Phase Overcurrent (OC)

This element is available for OCR mode “Recloser” only.
This element provides protection against overloads, phase-to-phase and three-phase short circuits.

8
The value of Ust setting cannot exceed the value of Rated voltage configuration setting.

30
 OC protection consists of six (6) individual overcurrent elements providing three stages of protection for both
the Forward (Source+) and Reverse (Source-) power flow directions: OC1+, OC1-, OC2+, OC2-, OC3+, OC3-
.

OC1
Phase overcurrent low set element OC1 is designated to provide time delayed trips. It is enabled in any
selected sequence in the Overcurrent Reclosing element. „I“ (Instantaneous) stands for accelerated and „D“
(Delayed) for delayed step of overcurrent protection in an autoreclosing sequence.

OC2
Phase overcurrent low set element OC2 is designated to provide accelerated trips. If a sequence step in the
Overcurrent Reclosing Element is set „D“ OC2 element is disabled. If a sequence step in the Overcurrent
Reclosing element is set „I“ OC2 element is enabled.

OC3
Phase fault high set instantaneous element provides protection against phase high current faults with a
reduced number of trips to lockout. If there is no intention to reduce the number of trips to lockout at high
current faults, enabling this element is not recommended. OC1 and OC2 allow reduction of tripping time to any
desired value at high currents.
For details on available TCC refer to Table 20 of this guide.
OC3 element settings are described in Table 21.

Earth Fault (EF)

This element is available for OCR mode “Recloser” only.
This element provides protection against single phase and double phase earth faults.
EF protection consist of six (6) individual overcurrent protection elements providing three stages of protection
for both the Direct (Source+) and Reverse power flow (Source-) directions: EF1+, EF1-, EF2+, EF2-, EF3+,
EF3-.

EF1
Earth fault low set element EF1 is designated to provide time delayed trips. It is enabled in any selected
sequence in the Overcurrent Reclosing element. „I“ (Instantaneous) stands for accelerated and „D“ (Delayed)
for delayed step of overcurrent protection in an autoreclosing sequence.

EF2
Earth fault low set element EF2 is designated to provide accelerated trips. If a sequence step in the Overcurrent
Reclosing Element is set „D“ EF2 element is disabled. If the sequence step in the Overcurrent Reclosing
element is set „I“ EF2 element is enabled.

EF3
Earth fault high set instantaneous element provides protection against high earth current faults with a reduced
number of trips to lockout. If there is no intention to reduce the number of trips to lockout at high current faults,
enabling this element is not recommended. EF1 and EF2 allow reduction of tripping time to any desired value
at high currents.
For details on available TCC refer to Table 17 of this guide.
EF3 element settings are described in Table 18.

Phase and Earth Overcurrent Reclosing (AR OC)

This element is available for OCR mode “Recloser” only.
The AR OC element provides reclosing initiated by tripping of one of OC1, OC2, OC3, EF1, EF2 or EF3
elements. The user set delay between trip and reclose is called „reclose time“ (Tr) and can be set
independently for each trip in the sequence. If the fault is not cleared during „reclose time“, the recloser will
trip again. This will repeat a number of times until the fault is cleared or the AR OC element reaches the end
of the user defined reclose sequence. At this point the recloser remains open and will no longer reclose
automatically. This is known as „lockout“ and the recloser can only be closed by local or remote operator
command, which clears the lockout condition.
AR OC settings are described in Table 25 and Table 26.

Reset time
The Reset time setting in the autoreclosing element controls the time elapsed between the closing command
execution generated by the relay to the breaker and the time the auto-reclose function resets to the initial cycle.
This timer is used to withstand fault restrikes in case an intermittent fault has been detected.
The First closure time setting controls how quickly autoreclosing will be enabled after an operator (local or
remote) closing command is executed.

Reset time for autoreclosing sequence

The Reset timer for the autoreclosing sequence starts counting when the close command is initiated by the
AR OC protection element that has been executed and no fault current is detected after closing. If the

34
 measured current does not exceed the pickup setting and the Reset timer stops counting, a current reclosing
cycle will be continued. In the case that, after closing, the measured current does not exceed the pickup setting
within the Reset time period, a new autoreclosing sequence will be enabled and will be executed for
consequent faults. The Reset time counter starts counting from zero for each automatic closing event in an
autoreclosing sequence.

First closure time (SST timer)

The Single shot to lockout algorithm is supported by the AR OC element. This function allows tripping and
lockout (preventing autoreclosing) if a fault has been detected by the operator during the First closure time.
The Single shot to lockout function will be disabled in case “Unconditional AR” is selected for First closure
mode. Recloser can make up to 4 closing operations including the first close initiated by operator.

Overcurrent Interruption Detection (OCID)

This element is available for OCR mode “Sectionalizer” only.
This element provides detection of the overload, phase-to-phase and three phase short circuit fault passage
and interruption due to operation of upstream device. OCID operates according to definite time TCC.
OCID settings are described in Table 27 and Table 28.

Loss of Supply Autoreclosing (AR LS)

The AR LS element provides reclosing initiated by the LS element tripping.
The delay between power supply restoration and reclose is called „reclose time“ (Tr). Tr time setting is
configured by the user. If loss of supply occurs again prior to reset time expiration, the recloser will trip again
and will not reclose automatically. This is known as „lockout“ and the recloser can only be closed by local or
remote operator command, which clears the lockout condition.
AR LS settings are described in Table 37.

REZIP
Rezip is the automation algorithm that enables complex distribution network automation. Rezip can be used
in networks where the recloser application is not possible due to protection coordination restrictions. The
algorithm is initiated by an upstream recloser trip. Once the loss of supply is detected, all Rezip reclosers will
trip during recloser dead-time. When the recloser closes, it restores supply to the closest Rezip recloser(s). It
activates the AR LS timer and after a preset time Rezip reclosers will close restoring the power supply to
downstream Rezip recloser(s). Immediately after closure Rezip the recloser(s) are operating in Instantaneous
protection mode and if any of them detects the fault, it will trip before the upstream protection device will. By
the time next Rezip recloser is closer by the AR LS, the upstream Rezip OC/EF protection is disabled, so no
grading between Rezip reclosers is needed.

13
In Rezip mode this setting has a fixed value and is unavailable (hidden).

38
 The algorithm provides the set-up simplicity of a traditional sectionalizer and at the same time reducing the
fault clearing time and network reconfiguration time application in far more complex networks and provide an
unlimited number of sections to limit the number of customers affected.

Rezip is applicable in meshed grid automation schemes together with ABR functionality. Rezip enables the
building of self-healing networks where it is not possible with conventional reclosers and sectionalizers.

Zone Sequence Coordination

The AR OC provides Zone Sequence Coordination (ZSC). ZSC forces the AR OC element to step to the next
count in the reclose sequence on reset of all protection elements if it detects a downstream protection device
has operated. This functionality is required for applications where a fuse-saving philosophy is used.

Hot Line (HL)

This element consists of two sub-elements which provide protection against short circuit faults during Hot Line
maintenance. It generally has more sensitive settings than corresponding OCR settings and it has no reclosing
functions. HL consists of two Overcurrent elements, one for Phase Overcurrent (HLOC) and one for Earth
Fault (HLEF). Operation of either element results in the trip to lockout.
HL settings are described in Tables 43-46.

Automatic Backfeed Restoration (ABR)

Automatic Backfeed Restoration is used to automatically close a normally open recloser if it detects a source
(via the SD element) on the either side of the recloser and absence of a source on the other side.
ABR function is designed to provide maximum safety for operators and equipment. Restoration disarm function
will prevent circuit-breaker closing for the ABR function in case power supply is absent from both sides longer
than specified Restoration disarm timeout (Trd) setting.
This element is only applicable for ring line type reclosers.
ABR element settings are described in Table 77.

Close Condition Verifier (CCV)

The Close Condition Verifier element controls breaker closing requests generated from local or remote
interfaces, an input/output module, or protection elements. If the network situation complies with the CCV
closing settings, closing is unblocked and vice versa.
A Hot tag for side + or – is generated if the Source Detector identifies that a source is found and the Voltage
Reclosing Control element identifies that the power quality is within the acceptable limits.
A Dead tag for side + or – is generated if the Source Detector identifies that a source is lost.
The CCV functionality can be Enabled or Disabled via the configuration menu. The CCV element settings are
described in Table 78.

Synchronization Indicator (SI)

The Synchronization Indicator is active only if the CCV setting Hot+ / Hot- allowed = Enabled. The SI element
monitors voltage magnitude and phase angle differences from both sides of the recloser. The CCV element

48
 will allow breaker closing if the voltage magnitude and phase angle difference is static and both parameters
do not exceed the predefined thresholds described in Table 79.

Fault Locator (FL)

This element calculates three data points:
• Xf – estimated distance from the recloser to the fault location in kilometers;
• X1_fault – estimated positive sequence reactance of the fault in primary ohms;
• X0_fault – estimated zero sequence reactance of the fault in primary ohms.
These points are calculated based on the selected phasor (phasor selection method is developed by Tavrida
Electric). Fault details are available in case of short circuit fault dropout or the recloser open to lockout after
unsuccessful reclosing. The indicated value of the estimated distance to fault (Xf) is limited with maximum fault
distance setting. Values indicated are updated after one of the OC1, EF1, OC2, EF2, OC3, EF3, SEF pickups
firstly in autoreclosing sequence.
Data points calculated based on the optimal phasor are available locally and remotely (in Event log, System
status, or via SCADA).Data points calculated at the moment of the protection device pickup or the protection
device tripping are available via SCADA only. Full list of the indicated data is presented in Table 80.

Cold Load Pickup (CLP)

In some cases, when power supply is restored after prolonged outage, this results in greater than normal
power demand. The main cause of this problem is the large number of electric heaters, furnaces, refrigerators,
air conditioners and other thermostat-controlled loads. Higher current is often seen by protection as short circuit
or overload, that result in circuit breakers automatically tripping to protect the system from overload, and the
power goes off again. The CLP element enables temporary increasing current pickup setting to sustain cold
load current and avoid tripping without compromising protection sensitivity. This functionality is applicable for
radial recloser as only in this case can the duration of power interruption for a group of customers be observed.
CLP settings are described in Table 83.

4.2 Measurement
Overview
The Main Processor gets the analog signals from the Outdoor Switching Module current and voltage sensors,
converts them into digital format, and filters it for Harmonic content. The RMS values of the filtered signals are
used for protection and indication as shown in the table below.

Signal filtering effectively rejects higher harmonics. Phase current measuring channels are additionally
equipped with inrush filters.

Inrush Filter
Reclosers described in the current product guide incorporate a unique inrush filter. This allows filtering of
magnetizing currents occurring at energizing transformers or distribution feeders with step-down-transformers.
In contrast to the widely used inrush restraint, which blocks the operation of protection for the period of inrush,
the filter leaves all protection active and sensitive to faults for the whole period of line energizing.
The advantages are:
• This feature makes it possible to select the settings of current-based protection elements based on actual
load and fault levels, not considering any side effects due to transformer load energizing;
• If, after maintenance closing or performing backfeed restoration for a faulty feeder part, the fault clearing
time is significantly reduced as all protection elements operate correctly without any delays.
Figure 26 and Figure 27 demonstrate the comparison of current measurement results at load energizing
captured by the recloser without and with inrush filter enabled.

4.3 Communication
Overview
Indication and control are provided through the following interfaces:

• Personal Computer Interface (PCI)

• Telecommunication Interface (TCI)
• Digital Input/Output Interface (IOI)
• TELARM dispatcher Interface (TDI)

In the „Local“ mode, the recloser is controlled via the MMI or PCI. In the „Remote“ mode the recloser is
controlled via TCI, TDI or IOI. Indication is provided via all interfaces in both modes.

Personal Computer Interface (PCI)

The PCI provides Indication and control via a PC (with installed TELARM software). The connection is
established via the USB port located on the front the Control Panel Module (CPM), RS-232 serial port, RJ45
interface of Wired Ethernet module, ST interface of Optical Ethernet module, WiFi module, or Bluetooth
module.

The PCI provides the following functionality (refer to TELARM software):

• Data upload/download;
• Firmware upload.

Uploading/Downloading data
Data can be uploaded/downloaded via the PC (refer also to the description of the on-line mode of TELARM
software) when the communication link is established. The communication link is password protected. The
password is configured via the PCI at the time of the first communication session and stored in the MPM flash
memory. If the control signal „Erase passwords“ has been activated the password is erased. A new password
can be uploaded from the PC during the next communication session.

Uploading firmware
A PC with installed TELARM is required for firmware uploading.

Telecommunication Interface (TCI)

TCI is an embedded RTU interface that can be used for remote indication and control.
The RTU is connected to the SCADA via a radio modem, phone modem, GSM modem, RS485-RS232
converter or directly.
Available communication protocols are DNP3, Modbus and IEC 60870-5-104.

52
 Digital Input/Output Interface (IOI)
The IOI provides control and indication via the digital Input-Output Module (IOM). The IOM provides 12 digital
inputs and 12 digital outputs for SCADA control and indication. Each input/output function is individually
customizable.

4.4 Remote Engineering

The TELARM Dispatcher Interface (TDI) enables multiple recloser connections to Tavrida Electric TELARM
Dispatcher® for remote control and supervision. TELARM Dispatcher can be installed on one or multiple PCs
with full or limited access to all or some of the reclosers. Connection via Internet or Local Area Network (LAN)
is available. Physical connection of an RC5_4 to the Internet can be done via wireless connection - GPRS
modem (Figure 28) or wired connection - USB-Ethernet module (Figure 29).
Both the RC5_4 recloser control(s) and PC(s) with TELARM software can connect to RC Internet Server
software (RCIS). This software provides communication between a PC and multiple RC5_4. RCIS itself is a
Windows® service. Connection between TELARM software and RCIS is protected with SSL encryption.
Individual certificates are issued for each PC with TELARM which will connect to RCIS.
Benefits of using a TDI are the following:
• Remote control is available even without a SCADA system in place (or as backup for existing SCADA
system).
• SCADA is usually available in dispacther centers only. With TDI regional operators can check protection
devices remotely without any support request form the Dispatcher Center.
• Potential problems can be identified and eliminated faster because all logs from protection device, including
Event log, detailed Fault profile and fault oscillography are available remotely and can be analyzed by an
operator immediately after protection device has operated.

Auxiliary VT Installation
Auxiliary voltage transformer should be installed on a dedicated VT holder of a mounting kit.
Line connections to auxiliary voltage transformer should be performed in accordance to a VT technical manual
by trained personnel who are familiar with the equipment.

Earthing
ATTENTION! The Outdoor Switching Module, its mounting frame and the Recloser Control should be
connected to the same earthing bus using 12mm nuts and bolts tightened to 50 Nm.
Earthing points on the OSM15/25_Al_1 and the RC5_4 are shown below.

Figure 49
Earthing terminals position

ATTENTION! Make sure that the system impedance to ground is less than 5 ohms. System impedance to
ground can be measured on site using special equipment or previously measured value for particular
grounding bar can be provided by the utility. In case this requirement is not met it may lead to death or injury
to people during operation.

76
 It is recommended to arrange high voltage assembly earthing as it shown in Figure 50. The Outdoor Switching
Module, mounting frame, auxiliary supply VTs should be earthed using separate earthing jumpers connected
to the common earthing bus. Surge arresters grounding wires should be connected to special earthing
provisions placed on surge arresters holders.

Figure 50

section. Aerial connectors and fasteners are made of stainless steel. The clamp is made of Sn-Bi coated brass.

Figure 51 Figure 52
Aerial connector Conductor connection via aerial connectors

Tightening torque of connector nuts is 20±1 Nm.

77
 Protective covers can be used to protect connections against the environment (Figure 53 and Figure 54).If
cable diameter is more than 10 mm, the cone end of each cover should be cut to the corresponding diameter
to fit the cable tightly (Figure 55).

Figure 53 Figure 54
Aerial connector with bird protection Aerial connector with bird protection

Figure 55
Aerial connector with bird protection

NEMA Connectors
Two-hole and Four-hole NEMA palm connectors (Figure 56) provide a reliable connection to power line of any
type of conductors treated correspondingly.
NEMA connectors are preinstalled and tightened the Outdoor Switching Module terminals during assembly.
The power line connection can be done using the M12 bolts and nuts (not supplied). It is recommended to use
HDG or stainless steel M12 fasteners and tin-coated cable lugs for power line connection to prevent corrosion.

Figure 56
NEMA palm connectors

Tightening torque for power line connection depends on M12 fasteners material used, but not less than 40
Nm.
Surge arresters and auxiliary VT HV terminals connection can be done directly to NEMA terminals.
Special NEMA protective covers can be used to protect line connections against the birds or aggressive
environmental factors (Figure 57).

RC5_4 Connection to Auxiliary Supply

ATTENTION! Auxiliary supply VT connection wire should not be earthed inside the VT secondary
compartment.
Before the auxiliary supply from a pole mounted VT is connected to the RC5_4, resistance measurement
should be performed. Switch digital Multi-meter to the Ohm metering mode and enable beeping signal.
Connect one electrode to the earthing bar (with the connected VT base earthing bar) and second electrode to
both connection wires (one by one or to both of them simultaneously). Resistance should be infinite, sound
signal should not appear.
Resistance measurement is not performed in case an external AC/DC supply is used.

79
 ATTENTION! Corresponding AC1 and AC2 earthing jumpers should be removed before external AC/DC
source with predefined neutral is connected to the RC5_4.
After the main line is powered, the commissioning engineer should make sure that the auxiliary supply is
connected correctly. The auxiliary supply voltage should be checked by digital voltmeter.
For that purpose the RC5_4 battery switch should be set OFF, corresponding AC switch (both switches if two
supply options is used) set ON.
Measured AC voltage at terminals 1-2 and 8-9 (in case two VTs are installed) should not exceed the limits of
85-265 V.
Connection terminals for the Recloser Control auxiliary power supply are shown below (Figure 59).
