1. INTRODUCTION
40 years of experience in production of busbar (ZSZ) and breaker failure (LRW)
protections of our specialists, supported by constant technical cooperation with the power
sector enabled us to develop devices, that fill in all the market expectations, including
those defined in the standards of Polish Power System Operator (PSE). In order to meet
the needs and demands set up by users, we offer a new device – busbar protection TSL-9
type, functioning as a busbar and breaker failure protection – which was developed basing
on rich experience in production of previous models, having a greatest focus on the latest
available technologies. The below catalogue represents only brief information, describes
basic functions and principles of operation. It does not contain full description enabling
designing and further exploitation of electric circuits using TSL-9r. Extended materials can
be provided on demand.

2. APPLICATION OF THE DEVICE.

The Busbar Protection is meant for quick and selective tripping of all bays of specified
system, or a whole busbar section in case of busbar fault. The range of operation of this
protection covers: busbar, busbar isolators and breakers. The range of operation is limited
by the place of installation of current measuring transformers.

The Breaker Failure Protection is meant for quick and selective opening circuit breakers
on the substation in case of fault (not opening) the circuit breaker in a specified bay
despite tripping impulse from its protection. In such instance the device – after specified
time T1 – sends a repeated tripping impulse to this circuit breaker. After unsuccessful
attempt to open that circuit breaker the device – after time T2 – opens all the circuit
breakers of bays connected to the same system or busbar section.

Basic features of the device:

 the device can be used for substation working in any type of arrangement,
 the device consists of one central unit and appropriate (depending on number of
bays of the substation) number of bay units,
 the device can operate as:
o a busbar protection,
o as a breaker failure protection,
o execute both functions simultaneously,
 the modular-chassis construction of the device enables its adaptation to a changing
arrangement of a substation when it is expanded by new bays,
 universal modules enable easy adaptation of the device to a change of the
transformation ratio, by a programmable change of the devices setup,
 two independent tripping circuits for each circuit breaker of the substation,
constructed basing on solutions used in RSH-3 relay (“fast tripping” relay), enable
breaking – in emergency situations – current of the circuit breakers coil,
 two criteria for defining the circuit breaker position: basing on current flow and
auxiliary contacts,
 two independent sets of activation inputs from protections working in different
circuits of auxiliary voltage
 possible one- and two-bit representation of the state of isolators and breakers,
 programmable operation algorithm accordingly with arrangement of the substation
 change of the setup can be done with a notebook.
 Built in internal events recorder

TSL-9r

 Built in internal fault recorder.

ZPrAE-Edit functional application is delivered along with the TSL-9 device. It

enables configuration and handling of the device as well as visualisation of current
waveforms from the internal fault recorder.

The device enables transmitting of data into local control system of a substation,
and enable remote, on-line communication with the device: observation of its state,
reading of recorded data and change of setup.

3. PRINCIPLE OF OPERATION.
3.1. Principle of operation of the busbar protection.
The busbar protection is equipped with two independent measuring circuits.
The first one – (of a system) working individually for a busbar system (section),
operates on a basis of comparison of current phases and amplitudes, covers bays
of a given system or busbar section. It becomes activated, when current phases of all bays
are concurrent and value of the differential current exceeds set value. Concurrence
of current phases is established within the first 2 ms for each half period, what clearly
identifies internal fault. Phase concurrence after this time does not cause operation of the
measuring circuit as it may result from saturation of current transformers in case of
external fault. Thanks to such solution the current transformers can be saturated up to
5 times, and the protection will continue to operate selectively.
The second one – (of a sum) operates on the differential current basis and covers
all bays of a substation together, regardless which system they are connected to.
It becomes activated when the differential current exceeds set value. This measuring
circuit operates always during internal fault on the busbar.
The value of starting current is set accordingly with the primary current of the
busbar in range 100 – 10000 A.
The busbar protection sends out tripping pulses only if for the same phase both
measuring systems operate (based on the two out of two criterion). In this case the
protection generates tripping pulses for all bays of the switchgear connected to a given
system, regardless values of current flow in those bays. Thanks to solutions and
algorithms used, as well as fast controlling relays the time to operate is less than 10ms.
The Busbar protection is fully selective and operates correctly even in case of faults
happening during re-switching of the switchgear, as well as faults between transformer
and circuit breaker in the busbar coupler bay. The protection also identifies faults in the
dead zone of the outgoing feeder – between current transformer and a circuit breaker.

3.2. Principle of operation of breaker failure protection

The primary criterion for activation of the breaker failure protection is coincidence
(synchronous occurrence) of:
- tripping impulse from protection of a given bay,
- information that the circuit breaker is closed.
Overrun of the preset permissible duration of this coincidence denotes, that the circuit
breaker has not opened, and in order to stop fault current inrush to the point of fault all
circuit breakers connected to this point must be opened.
The status of circuit breaker is determined by:
- control over volume of current flow through a given bay (current criterion - KP)

2 ZPrAE Sp. z o.o.

 TSL-9r

- control over status of auxiliary contacts of a circuit breaker of a bay (circuit breaker
criterion KW)

The circuit breaker failure protection operates in two stages. The first stage is a
repetition of the tripping impulse for its own circuit breaker. This operation is done
instantaneously or with a short delay time (T1) – the so called “re-trip”.
After unsuccessful attempt to open its own circuit breaker in the first stage of LRW
operation and following the lapse of the second stage time (T2), tripping pulses for all
circuit breakers connected to the same busbar system (section) are generated. Those
tripping pulses are always generated in both tripping circuits.
There are separate time delay elements, T1 and T2, provided for each phase and
for three-phase activations coming from protections “with” and “without current”.
Time delay elements operating in circuits in which current flow is used as the
criterion for indicating the CB status have two adjusting elements (T2.J) whereas the
circuits in three-phase activations from protections “without current” which as the criterion
of CB status use its auxiliary contacts, have a separate adjusting element (T2.W).

4. CONSTRUCION OF THE DEVICE

The construction and algorithms of operation enabled creating a device, that is
technologically advanced, operates fast and reliably being user friendly at the same time.
The TSL-9r device consists of terminals, each of which serves one substation bay,
hereinafter referred to as bay units (BU), and of one central unit (CU) – controlling
cooperation of the bay units. Additionally the central unit acts as an event recorder,
ensures communication with the “outer world” and enables full configuration of bay units.
Each bay unit is connected to the central unit with a fibre optic cable. The central unit as
well as the bay units are produced in chassis to be mounted in a swing frame of a cubicle.
Connection of external cables is ensured by terminals mounted on the back wall of the
device. An LCD touch panel and signalling diodes are mounted on the front panel of BUs
and the CU.

4.1. Dimensions of the device.

The TSL-9r devices are mounted in a 19” EURO chassis made from chromed
aluminium, providing sufficient protection for EMC interferences.
The central unit of TSL-9r is mounted in a 6U chassis. Bay units of the TSL-9r are
mounted in chassis 3U high, or in a case of versions with doubled tripping circuits - 5U.
Bay units of TSL-9r E are fitted inside a half of the 3U chassis what enables mounting of
two such units in one 3U chassis.

TSL-9r

When the function of busbar protection is active the basic screen provides
information on error (differential) current in % of primary current of the busbar. Changing
the preview of error (differential) current measured for the whole busbar system, and each
system separately is done by pushing the arrow situated next to values of measured
currents displayed on the screen.

Touch screen buttons, enabling the following operations are located In the bottom of
the screen:
- RESET – confirmation of operation of the protection and resetting signals from the
central and all bay units
- ZSZ – changing preview into setup of busbar protection (possible only for devices
with active function of busbar protection)
- OPTIONS – preview of i.a. mimic diagram of specified bays as well as blocking and
unblocking of functions.
- SIGNALS – preview of chosen interference signals from the device.

C – Diodes of supply, errors and operation.

On the right hand side of the devices five diodes signalling state of operation of the
central unit are located. The two upper diodes inform about activation of ZSZ and LRW
functions. Green light means that function is active, yellow – disabled. The red diode in the
middle - “TRIP” - means that the device sent a tripping pulse. The yellow diode “ERROR”
stands for interferences of operation of the device. The last one – green diode “POWER”
means that the unit has power supply.

4.2.2. Back panel and terminals.

Terminals for the external connections are located on the back panel of the device.
The device is provided with plugs.
A – Power supply.
In order to increase reliability of operation the device is equipped with two power
supplying modules working in parallel each of which is supplied from two separate circuits
of auxiliary supply – primary and backup. Power of one supply module is sufficient to
supply the entire central unit.
B – Power system stabilizer.
The Module of the stabilizer ensures appropriate power supply of all modules in the
device.
C – Communication.
The MGB concentrator is responsible for external communication with a control
system or with a station computer. This module serves also as a main cache memory for
the events recorder. It enables archiving up to 10 thousand events with 1ms resolution.
The memory used is non-volatile, meaning that lack of power supply does not result with
erasing stored events. It is equipped with a real time clock, which can be synchronised
with superior control system of a substation or an optional GPS module. Digital recording
of data in the hub enables sending them to the superior control system.

The MGB concentrator can be maximally equipped with four transmission channels
on different physical layers: RS232, RS485, fibre-optic cable and Ethernet.
The Ethernet enables connection with maximally four independent users at the
same time. Each channel may operate in IEC 870-5-103 protocol or factory protocol ZP-6.
One of the channels may be used for communication with the GPS module. The RS485
connection is delivered in 2-conductor standard or optionally – 4-conducotor.
Communication in accordance with IEC 61850 protocol is provided by communication
module version MGB-9F.1, equipped with communication port with Ethernet slot, and with
two fibre optic slots.
The control systems of a station using communication protocols IEC 870-5-103,
IEC61850 have possibility to receive recorded events, reading current states of faults, and
steering, for example remote resetting.

As a standard the central unit is equipped with two 8-line isolated input cards meant
for receiving information about:
• State of the section disconnectors
• Remote reset and blocking of functions of the device.
Optionally, the device can be equipped in further configured input terminal card.

4.3. Bay Unit.

The bay unit is offered in five basic versions. The versions differ in number of input
and output cards as well as number and types of tripping modules. Due to such diversity
it is possible to provide protection for any arrangement type of a substation: three-switch
substations, system substations, mesh substations or substations with one-and-a-half or
two breaker arrangement. Version with double tripping cards can be used in substations
where separate circuits for ZSZ and LRW are required when one device executes both
functions.

• A – with activation and tripping pulses for each phase separately,

• B – with activation and tripping pulses for each phase and with additional tripping
pulses for the LRW function in one-and-a-half breaker arrangements,
• C – with 3-phase activating and tripping pulses separately for each function (ZSZ &
LRW),
• D - with activation and tripping pulses for each phase and separately for each
function (ZSZ & LRW),
• E - with 3-phase activating and tripping pulses.

The Euro-chassis of the TSL-9r bay unit contains a power supply, binary inputs,
current measuring circuit, logic and communication module, relay outputs and tripping
relays. Additionally, bay units in version A, B, C and D are equipped in a testing module
as a standard.

D – The testing module MTT.

Test terminals are mounted on the front panel of the bay unit. They are available
only after removal of a transparent shield, and activation by turning the switch into TEST
position. The currents on the side of current transformers are short-cut and current inputs
are lead to the test terminal. At the same time the tripping circuits are disconnected and
put through to the test terminal. The MTT module is not an obligatory equipment for proper
operation of the bay unit; however it is a standard equipment of the A, B, C and D
versions.

A – Power supply –MZT module.

The supply module operates as a recoupling device from among two supplying
voltages, supplying voltage for the mapping circuits and for the device.
B – Binary input module MTG.
5 modules of binary inputs, each with 8 lines in versions A, B, C, D or 2 modules
each with 8 lines in version E are used for input of mapping and activation signals into the
device.
C – Current module MAP
The device is equipped with four circuits for current measurement (three for phase
currents, and one for neutral).
D – Logic and communication module JPC.
Microprocessors built inside the JPC modules communicate with microprocessors in
MOP modules of the central unit via fibre-optic cables. The communication protocol is in
accordance with the IEC 870-5-103. The following information is transferred via the
protocol:
- enabling tripping of specified bays,
- configuration data,
- status of inputs and outputs,
- enabling remote blocking, resetting and testing of the device.

The MPR module consists of three groups each of which with 4 programmable
signalling outputs, the MPS module built in A, B, C and D versions consists of additional
8 programmable contacts (for example for supplementary tripping signals)
F – Tripping module MWK.
The modules are constructed basing on the RSH-3 relay – tripping relay, enabling
breaking of the circuit breaker coil current. The A version of the bay unit has two MWK
modules, each of which contains three tripping relays, enabling tripping each phase in both
circuits separately. The version C is equipped in two sets of three single-phase modules
for each tripping circuit. One set executes operations of ZSZ and the second one - those of
LRW. The E version has only one three-phase module for each circuit.

Picture. 4.16. Sample placement of TSL-9r units in centralized and decentralized arrangement.

4.3. Construction.
The TLS-9r device has a decentralized construction, adjusted for mounting in
protection cabinets for separate bays.
The bay units, however can be located in one cabinet together with the central unit
– in such centralised solution, the device can be provided as fully assembled in a cabinet
with a terminal strip for the connection of external wiring.

5. FUNCTIONAL SOFTWARE
Along with the TSL-9r user receives a functional software ZPrAE-Edit enabling
configuration and use. The installation package is delivered on a CD. It is possible to
determine password protected access levels.
The software enables:
- preview of current status of the bay disconnectors and breaker, as well as setup of
the bay,

ZPrAE Sp. z o.o. 13

TSL-9r

- display of current scheme of the entire switchgear,

- configuration of signalling diodes, touch screen of bay units and the central unit,
- configuration of auxiliary and signalling relays of bay units and the central unit,
- readout from the fault recorder and visualisation of recorded waveforms,
- readout from the events recorder.

The software informs user i.a. about status of the bay, i.e. about position of
disconnectors and breaker, tripping pulses from ZSZ (IWS), LRW (IWR), defective breaker
(UW), operation in the dead zone, interruptions in mapping (ZO), incorrect mapping (NZO),
lack of continuity of the tripping circuits (NOW), blockade of the breaker (BW), blockade of
the bay and failure of the bay (NSP)

Diode signalisation including status of diodes is presented on the left side of the
window. Each of the 8 diodes can be configured to represent chosen signal from the bay
unit’s signals list.
On the right side of the window following signals are displayed:
- ZSZ – green colour of the diode means that busbar protection is active and
operates properly, yellow colour means that ZSZ function is disabled.
- LRW – same as above, green colour of the diode means that breaker failure
protection is active and operates properly, yellow colour means that LRW function is
disabled. No light of the diode means that the device is not equipped with LRW system.
- ERROR – means that there is a problem with signals connected to the bay unit,
i.e. incorrect mapping, long lasting energizing impulse, loss of one of supplying voltages,
loss of mapping voltage or loss of communication with the central unit.
- POWER SUPPLY – informs about power supply for the device.

Picture.5.1. Software window „BAY PREVIEW”.

Present current flow is presented in the bottom part of the window. User may decide
on the way of presentation of current flow volume:
- as a percentage of nominal current of the current transformer I/In,
- in values on the secondary side of the current transformer Iw,
- in values on the primary side of the current transformer Ip.
Additionally user can block/unblock the bay unit (after entering 3-rd level password),
or reset signals (after entering 1-st level password).

6. FAULT RECORDER.
The central unit functions as a fault recorder, which is collecting binary and analog
data from bay units via fibre optic connections.
The data are gathered with maintaining mutual synchronism, and written in a cache
memory. In the moment of triggering the recorder data recorded in a specified set period
before the trigger are stored in a non-volatile flash memory. The data after triggering
moment are recorded for as long, as they reach pre-set recording time. The pre-trigger
time can be set with the ZPrAE-EDIT software.
The recorder is triggered by one of the below events:
- any external activation,
- exceeding of set current flow value in phase L1, L2, L3,
- exceeding of the set current flow value I0
- operation of protection
Parameters of recording:
- sampling frequency - 1kHz,
- maximal time of single record - 8 seconds,
- maximal number of stored records in cache memory– 100 (if this number of
records is exceeded, new records replace the oldest records stored)

Picture. 6.1. Main window of iREC software.

The software provided along with the device enables visualisation of the records
saved as a COMTRADE file.
Currents can be viewed in values of primary or secondary current of the current
transformers, or in relation to the rated current of the current transformers. An additional
practical option enabled by TSL-9r is a possibility to create virtual channels, for which the
waveforms are calculated based on real measurements (i.e. it is possible to create
differential current waveforms for a system or a section). File with the records presents
current waveforms of all bays, and binary signals of all inputs and outputs. It is possible to
filter out only chosen waveforms. As an example it is possible to filter out only the phase

that caused operation of the ZSZ in the analog channels, and in the binary channels to
choose only those that changed their status during the recording period.
