1.0 Formation of System Protection Department

The erstwhile Meters and Relays Department was carrying out three major functions viz.,

Meters, Relays and HV metering. In the advent of the Electricity Act, 2003, a need was

felt to restructure the Electric Supply Branch to segregate the activities as Field Operating

establishment, Customer Care establishment, Planning Establishment and Ancillary

Establishment for smooth working and flexibility in horizontal mobility of the personnel

for better utilization. Accordingly while restructuring the supply branch the Meters &

Relays Department was bifurcated into two departments as Meters Department under

Customer Care establishment (Supply Business) and System Protection Department

under Field Operating establishment (Wire Business) vide Administrative Order no. 359

dated 07.09.2011. The System Protection Department has been kept under the direct

control of Chief Engineer (Maint. / Work). System Protection department has started its

functioning from 22nd October 2011 and its office is located at 2nd

floor, T.T.C. building,

Wadala Depot.

1.1 Organization of the department:

The department set up is shown in the attached organization chart. Please refer

Annexure- I. The activities of the department are mainly related with five O & M

Divisions. Hence each zone of O & M Divisions is assigned to five Assistant Engineers.

2.0 Activities of System Protection Department :

The System Protection department is responsible for carrying out activities of testing and

maintenance of all the relays installed in various Receiving stations for the protection of

our 110 kV, 33 kV and 11 kV network. The discriminative tripping is the backbone of

any distribution system since it helps in isolating the exact fault area and thus avoids the

unnecessary revenue loss which otherwise would have incurred if the healthy network

also would have tripped along with faulty network. At present there are 61 nos. of RSS,

out of which 4 nos. are 110 kV RSS. In addition to the above 9 nos. of new RSS are in

pipeline and are expected to be commissioned in the recent future. Besides tripping

messages are also attended by the System Protection Department for investigation and for

taking corrective measures, if any.

TECHNICAL MANUAL AND WORK PROCEDURES

a ) TERMINOLOGY

1.0 Protective System: is a team of protection relays, circuit breakers, CT‘s, PT‘s,

Secondary control cables, trip circuit, battery system accessories etc.A combination of

protective gear designed to secure under predetermined conditions, usually abnormal, the

disconnection of an element of a power system, or to give an alarm signal or both.

2.0 Protective Scheme: The co-ordination arrangement for the protection of one or more

elements of power system.

3.0 Protective Relay: A relay is designed to initiate disconnection of a part of an electrical

installation or to operate a warning signal, in case of a fault or other abnormal condition

in the installation. A device designed to produce sudden pre-determined changes in one

or more electrical circuits after the appearance of certain conditions in the electrical

circuit controlling it.

3.1 Relays are compact analog, digital and numerical devices that are connected throughout

the power system to detect intolerable or unwanted conditions within an assigned area

such that to maintain a high degree of service continuity and limit the equipment damage.

4.0 Protected Zone: A portion of a power system protected by a given protection system or a

part of that protective system.

5.0 Main Protection: Protection normally expected to take the initiative in case of a fault in

the protection zone.

6.0 Back up Protection: Protection provided to act as substitute for the main protection in

the event of failure or inability of the latter.

22

6.1 Relay Back-up: An arrangement, which provides an additional relay using the same or

alternate principle of operation from that of the main relay (It is preferable to have

separate C.T. and if necessary separate P.T. for relay backup)

6.1 Circuit Breaker Back-up: An arrangement at the next which provides isolation from

source when circuit breaker nearest to fault fails to open or in case there is failure of the

secondary current or voltage. (It is usually of a time delay relay operated from the main

protection and connected to trip all the incoming feeders.)

6.2 Remote Back-up: An arrangement at the next station in the direction towards source,

which trips after a delayed time if the circuit breaker in the faulty section is not tripped.

7.0 Instantaneous Relay: A relay, which operates and resets with no intentional time delay.

8.0 IDMT Inverse Definite minimum time relay: An inverse time relay having an

operating time that tends towards a minimum definite value with increase in electrical

characteristic quantities.

9.0 Setting: The limiting value of a characteristic or energizing quantity at which the relay is

designed to operate under specified conditions.

9.1 Plug Setting Multiplier (PSM): A range of current setting for varying the relay

operating current provided in the relay.

9.2 Time Setting Multiplier (TMS): A means of adjusting the travel of the disk and thereby

varying the time of operation of the relay for a given value of the fault current.

9.3 Pick-Up (PU): A relay is said to pick-up when it changes from the unenergized position

to the energized position.

9.4 Drop Out: A relay drop out when it moves from energized position to unenergized

position.

10.0 Burden: The loading imposed by the circuits of the relay on the energized power source

or sources, expressed as the product of voltage and current (Volt –amperes or Watts if

PC) for a given condition which may be either at setting or at rated current or voltage.

23

11.0 Characteristic Curve: The curve showing the operating value of the characteristic

quantity corresponding to various values or combinations of the energizing quantities.

12.0 Residual Current: The algebraic sum of all the currents in a system is Residual Current.

13.0 Residual Voltage: The algebraic sum of all the phase to earth voltages in a system is

Residual Voltage.

14.0 Knee Point Voltage: The sinusoidal voltage of rated frequency applied to secondary

terminals of a current transformer, all other winding being open circulated, which when

increased by 10% Causes the exciting current to increase by 50%.

b) PRINCIPLE OF PROTECTIVE SYSTEM

Every electrical equipment is designed to work under specified normal conditions. In

case of short circuits, earth faults etc. an excessive current will flow the windings of the

connected equipment and cause abnormal temperature rise, which will damage the

winding. Further it may cause total shunt down of unit, which will result in heavy loss of

revenue.

A fault in electrical equipment is defined as a defect in its electric circuit due to which

flow of current is diverted from the intended path. Faults are caused by breaking of

conductors or failure of insulation.

Fault impedance is generally low and fault currents are generally high. During the faults,

the voltages of three phases become unbalanced and the supply to the neighboring circuit

is affected. Fault currents being excessive, they can damage not only faulty equipment

but also the installation through which the fault current flows.

There are several causes of faults occurring in a particular electrical system. Faults can be

minimized by improved system design, improved quality of equipment, better and

adequate protective system, better operation and maintenance etc. however, fault cannot

be eliminated.

c) FUNCTIONS OF PROTECTIVE SYSTEM

1) To sound an alarm, so that the operator may take some corrective action.

24

2) To close the trip circuit of circuit breaker so as to disconnect a faulty component

during an abnormal fault condition such as overload, under voltage, temperature

rise, unbalanced load, reverse power, under frequency, short circuit etc.

3) To disconnect the faulty parts as quickly as possible as to minimize the damage to

the faulty part and to prevent subsequent faults.

4) To localize the effect of fault by disconnecting the faulty part from healthy parts

causing least disturbances to the healthy system (to improve the system stability

and service continuity.

d) REQUIREMENT OF PROTECTIVE SYSTEM

Protective system should have following qualities

1.0 Selectivity: The protective system should discriminate between abnormal and normal

conditions. It is ability of protective system to determine the point at which the fault

occurred and should isolate the only faulty portion from remaining healthy system to

minimize or no damage to system.

2.0 Speed: Protective system should disconnect a faulty element as quickly as possible, in

order to improve power system stability, minimize the damage and to increase the

possibility of second type of fault development.

Fault Clearing Time = Relay Time + Breaker Time

= Fault Instant (Relay Pick Up) to Closing of relay contact

+ Closing of relay contacts to Final breaker OFF.

The relay time of fast relay is in order of few cycles. Modern protective relay has

operating time of about 1 cycle. For Inverse Definite Minimum Time (IDMT) relays,

relay time can be adjusted between 6 seconds to 60 seconds.

3.0 Sensitivity: It is capability of relay to operate reliably under the actual minimum fault

condition. It is desirable to have the protection as sensitive as possible in order that it

shall operate for low value of actuating quantity.

25

4.0 Stability: It is quality of protective system so that it remains inoperative and stable for

fault beyond the protective zone.

5.0 Reliability: The protective system should not fail to operate in event of faults in

protected zone. Also there should not be component failure of protective system.

6.0 Adequateness: Protection provided for any equipment should be adequate.

e) RELAY CLASSIFICATION:

1) Protection Relays: which detects defective lines, defective apparatus or other

dangerous conditions on Power system and gives commend to trip one or more

breakers which desired to operate. e.g. O/C, E/F, U/V etc.

2) Auxiliary Relays: This operates in response to operation of parent relays e.g. Master

Trip relay.

3) Monitoring Relays: Which verify the conditions on power system or in protection

system e.g. Trip supervision relay.

4) Regulating Relays: Which are activated when an operating parameter devices from

pre-determined limits e.g. AVR relay.

f) Classification of Relays according to operating Input quantity:

The BEST Undertaking has installed 100 MVA (110/33kV, YnYn0), 45 MVA (110/11-

11kV, YnZn11), 16-20 MVA (33/11kV, Dyn1), 16 MVA (33/11kV, Dyn1), 10 MVA

1.1.2 PROTECTION IN DISTRIBUTION SUBSTATION

Further, it is step down to 11-6.6 kV voltage levels by distribution transformers

11kV/415 Volts at DSS. 11kV network is connected in ring but operated in radials.

At DSS level, OCB/VCB of outgoing feeder has combined overload protection for

Overload on R & B Phase and earth fault on neutral circuit. OCB/VCB of transformer

feeder has combined overload protection for Overload on R & B Phase but earth fault

protection is kept without T/L fuse on neutral circuit for instantaneous Earth fault.

The method of tripping in DSS is ―Series tripping‖ i.e. the trip coils are operated directly

by CT‘s current. DSS breakers are normally provided with two O/L trip coils in R & B

phase and one earth fault trip coil in return neutral of three star connected CT‘s secondary

circuit. The time lag (T/L) fuses are connected across these trip coils, O/L trip coil and

earth trip coils are of size of 5 amps and 2 amps respectively.

Due to overload or short circuit or earth fault in network, 5 Amps / 2 Amps or more

current flows through the T.L. fuses of overload trip coil / E/F trip coil respectively. TL

fuse blows and current starts flowing through O/L / E/F trip coil which causes tripping of

circuit breaker.

1.1.3 PROTECTION IN LV NETWORK

Transformer secondary is connected to LV bus bar through copper links and transformer

breaker protects HV side of transformer.

Distributors are provided with 315 Amps HRC fuses at LV boards and LV pillars which

provide protections against faults on distributors.

At service position, 400A / 200A fuse base are provided with 400A and 200A HRC

fuses. At large LV installations, switch fuse unit of appropriate size is provided.

Re-wirable fuses in branch cutouts of 100A, 63A, 32A, 16A are provided at branches

feedings meters. These branch cutouts are provided on Meter Boards to protect the meter

against fault in the consumer‘s installation.

1.1.4 PROTECTION OF 33kV/22kV CABLES:

a) UNDER VOLTAGE RELAY :

Any fault occurring on 33KV/22KV cable operates protection gear at TATA‘s Receiving

Stations. When 33KV/22KV supply fails we get the indication at the Receiving Station

and Supervisory/ System Control Room. At Receiving Station, we are having under

voltage relay which gives indication of supply failure on 33KV/22KV side.

b) DIRECTIONAL OVER CURRENT & EARTH FAULT RELAY :

Normally B.E.S.T. network is radial right from Tata‘s transformer up to LV network.

But, when carrying out operation for load transfer, we keep power transformers in

parallel either of the same Receiving Station or of different Receiving Stations. In the

said circumstances if a fault occurs on 33kV / 22kV cable, then the affected bus section

will be reverse fed by other power transformer (after switchgear at the TATA‘s

Receiving Station has tripped). To avoid this, we use Directional over current and earth

fault relay, which operates (indicating power flow is reverse i.e. from 11kV to 22/33 kV

side). This protection scheme is typically employed on110kV & 33kV sides in 110kV

RSS.

35

b) RESTRICTED EARTH FAULT RELAY : (REF RELAY)

Restricted Earth Fault (REF) Relay operates on the Merz-Price Circulation current

principle with CTs of identical ratio and ratings in LV CT and NCT. This relay operates

only when fault occurs between secondary of the power transformer up to 11KV bus bar

and neutral of transformer which is protection zone for REF relay. The relay is connected

across the parallel combination of CTs in High Impedance mode.

36

Differential relay is used to detect any internal fault on HV or LV winding of the

transformer. This relay operates on the Merz-Price Circulation current principle. As long

as there is no fault in the transformer then current on 33kV / 22kV and 11kV side is the

same. So there is no current in the differential relay.

Due to fault in the transformer (Internal Faults), there is an imbalance between primary

current and secondary current, which operates the relay. Thereby, cause tripping of 33 kV

/ 22 kV and 11 kV breakers to isolate power transformer.

Protection gear of differential relay is designed with due care of No load current, Inherent

phase shift in winding of transformers and Change of turns and so current ratio due to

OLTC operations.

During External Faults: when there is external fault in network of transformer, fault

current flows in both HV as well as LV side CT‘s causing resulting zero current in

operating coil of differential relay.

37

c) BUCHHOLZ RELAY :

Buchholz relay is fitted between the transformer main tank and conservator. If any fault

e.g. core bolt insulation failure, short circuit in laminations, loss of oil due to heavy

leakage occurs in the HV or LV winding of transformer resulting in local heating of oil

and gas formation, then these gases is trapped in the Buchholz relay. It cause operation of

upper float and gives an alarm, which give some idea of nature of fault.

If serious nature of fault inside the transformer due to short circuit between phases,

winding earth faults, bushing failure it operate both floats provided in buchholz relay and

gives the trip command to primary & secondary breakers of transformer.

d) PRESSURE RELEASE DEVICE : (PRD)

This device operates during excessive pressure developed in the transformer main tank

due to internal fault occurred in it & it will give the direct tripping command to primary

& secondary circuit breakers.

e) OIL SURGE RELAY : ( OSR)

This relay is fitted between the OLTC & Conservator. If any fault occurs in the OLTC of

transformers resulting in local heating of oil and gas formation, then these gases is

38

trapped in the OSR & it will give the direct tripping command to primary & secondary

circuit breakers.

Trip commands of Buchholz relay, PRD and OSR are wired up through Ratio Differential

relay to get disturbance recordings at time of fault.

1.2 INSTRUMENT TRANSFORMERS

The magnitude of current and voltage in a power system are usually too high to be

handled by the secondary equipments like measuring instruments and relays, control

circuits. Therefore, the instruments produce a scaled down replica of the primary input

quantities within the accuracy. The measuring instruments and protective relays are

connected in secondary circuit of instrument i.e. current and voltage transformers.

1.3 CURRENT TRANSFORMERS (CT)

Primary current is not controlled by condition of secondary circuit in current transformer.

Hence, primary current is dominant factors in the operation of current transformer. The

performance requirements of the instrument transformers depend upon their applications.

CTs classified into three basic types.

39

a) Measuring Current Transformer: Measuring Current transformers used for

measurement handle steady current closed to rated values. Ammeters, Energy Meters etc

are connected in measuring CT circuit.

Measuring CTs are specified in term of Accuracy Class, rated VA Burden and Instrument

Safety Factor (ISF).

Instrument Safety Factor:

It is the ratio of instrument limit primary current to the rated primary current. Instrument

limit current of a metering current transformer is a maximum value of primary beyond

which current transformer core becomes saturated.

Accuracy Class –0.1, 0.2, 0.5S, 0.5, 1, 3

VA Burden – 5, 10, 15, 30

ISF – 5, 10

For metering core, we have adopted 0.5 class for outgoing feeders and 0.5S for HV & LV

side CTs with ISF = 5.

b) Protection Current transformers: Protection current transformers used for protection

handle fault quantities in multiple of rated values. Protection relays, trip are connected in

protection CT circuit. Current transformers step down current high value to low value.

Protection CTs are specified in term of Class, rated VA Burden and Accuracy Limit

Factor (ALF). Standard errors are specified at rated current and ALF times rated current

with rated burden connected. For given CT, VA and ALF are inversely related. If

connected burden is less than rated, ALF would increase.

Standard Error Class - 5P, 10P, 15P

ALF - 5, 10, 15, 20, 30

VA Burden – 5, 10, 15, 30

For protection core, we have adopted 5P20 class, 15 VAfor outgoing feeders, HV & LV

side CTs. This means that CT will have a Composite Error (difference between Ideal Sec

40

current and actual sec current) of +/- 5% at 20 times rated current and a ratio error of +/-

1% at rated current with rated connected burden of 15VA.

c) Protection CTs for Special Application: For balanced protections like Differential,

REF, where balance is required between the associated CTs with close tolerance.

For such applications, CTs of class PS are used which are specified in term of Knee Point

voltage (Vk), Magnetising current (Im) at Vk and at Vk/2, CT secondary resistance (Rct).

For class PS CTs, the turn ratio errors are limited to 0.25% which helps in maintaining

balance between the protection systems during the fault condition.

Specification / Name plate of PS class core:

CT ratio = 300/5

Vk>= = 104 Volts

Im at Vk/2 = 50 mA

RCT at 750C = 0.3 ohm

Magnetizing Characteristic of CT: the magnetizing characteristic of a CT is a plot

between secondary applied voltage the corresponding magnetizing current taken by the

CT.The excitation curve can be divided into Ankle point, linear region, Knee point and

saturation.

The knee point is defined as a point on the excitation curve where a 10% increase in the

secondary voltage would cause 50% increase in exciting current.

1.4 EFFECTS OF SECONDARY OPEN CIRCUIT:

The primary current of CT is independent of its secondary loading. With shorted

secondary (directly or through the connected burden), the counter flux produced by the

secondary keeps the core flux below the saturation level.

Load current in electrical system always flows through CT primary. If the secondary gets

open circuited with the primary carrying current, the entire primary current will behave as

excitation current and is spent in magnetizing the core, producing high core flux. This

results in increased secondary voltage. This develops extremely high pulses of voltage

which may not be measured by voltmeter. But this voltage may breakdown the CT

insulation and may cause accident to personnel. That is why CT secondary should not

be kept open and should always be shorted.

1.5 CURRENT TRANSFORMER DETAILS:

We are using different types of CTs in systems from 110kV to 11kV voltage level. CTs

are specified for Insulation level, rated primary current and Short Circuit Withstand

current.

Service Voltage: System Voltage in which CT is to be installed e.g. 11kV, 22kV, 33kV

and 110kV etc.

Rated primary current: It is value of rated current of equipment at CT location which CT

should carry continuously.

Rated Secondary current: Rated secondary current is specified as 1A or 5A. It is preferred

to use 5A as secondary current for indoor panels where internal wiring length is short and

1A where wiring length i.e. control cable length is long. It is value of rated current of

equipment at CT location which CT should carry continuously.

Short Time Withstand Current: It is maximum fault current value which CT can

withstand for short time rated. A current transformer is overloaded while system short

circuit currents are flowing and will be short-time rated. Normally system fault current is

considered as value of STC even though real fault current is less.

42

Standard times for which the CT must be able to carry rated short-time current (STC) are

0.25, 0.5, 1.0, 2.0 or 3.0 seconds. Specified values for STC are 18.4 KA for 3 Sec for

11kV CT and 26.3KA for 3 Sec for 33 kV CT.

1.6 CURRENT TRANSFORMER TESTING

CT is tested for Ratio, Polarity and Knee Point Voltage. Earlier CT testing is carried out

by Conventional method i.e. using primary injection set, dimmer, energy meter, voltmeter

and ammeter. This method involves typical connection of many conventional instruments

and manual calculations.

Recently, Omicron make CT Analyser set was purchased. Voltage and current is injected

from secondary side of CT. Values of current and voltage is sensed at Primary and

secondary terminals of CT. Final results are derived from these values in CT Analyser.

1.7 POTENTIAL TRANSFORMERS (PT)

Whenever the values of voltage in a power circuit are too high to permit convenient

direct connection of measuring instruments or relays, coupling is made through voltage

transformers. Voltage transformers are much like small power transformers, differing

only in details of design that control ratio accuracy over the specified range of output.

The performance requirements of the instrument transformers depend upon their

applications. PTs classified into three basic types.

a) Measuring Voltage Transformer: Measuring VTs used for measurement handle steady

voltages closed to rated values. Voltmeters, Energy Meters etc are connected in

measuring VT circuit.

Measuring VTs are specified in term of Voltage Ratio, Accuracy Class, Rated VA

Burden and Rated Voltage Factor.

Accuracy Class –0.1, 0.2, 0.5, 1, 3

VA Burden – 5, 10, 15, 30

Voltage factors, with the permissible duration of the maximum voltage is 1.2 continuous

& 1.5 for 30 sec between line and earth in an effectively earthed network.

Rated Voltage Factor (Vf): The voltage factor (Vf) is an upper limit of operating voltage,

expressed in per unit of rated voltage. This is important for correct relay operation and

operation under unbalanced fault conditions on unearthed or impedance earthed systems,

resulting in a rise in the voltage on the healthy phases.

For metering core, we have adopted 0.5 class for HV & LV side VTs with Voltage factor

= 1.2 continuous & 1.5 for 30 sec. This means that VT will have a % Ratio Error of +/-

0.5% at 80% to 120% of rated voltage with rated connected burden of 50VA.

Protection Voltage transformers: Protection VTs used for protection to handle fault

quantities in multiple of rated values. Protection relays are connected in protection VT

circuit. VTs step down high voltage value to low voltage value.

44

For protection purposes, accuracy of voltage measurement may be important during fault

conditions, as the system voltage might be reduced by the fault to a low value.

Protection VTs are specified in term of Voltage Ratio, Accuracy Class, Rated VA Burden

and Rated Voltage Factor.

Accuracy Class –3P, 6P

VA Burden – 5, 10, 15, 30

Voltage factors, with the permissible duration of the maximum voltage is 1.2 continuous

& 1.5 for 30 sec between line and earth in an effectively earthed network.

For protection core, we have adopted 3P class, 50 VA for HV & LV side VTs. This

means that VT will have a % Ratio Error of +/- 3% at 5% to 1.2 times rated voltage with

rated connected burden of 50VA.

1.8 CAPACITOR BANK PROTECTION

1.8.1 Under-Voltage protection:

During power failure, it is essential that capacitor bank should trip and should not be re-

energized till it discharges to safe value of 50 Volts or less. This is reason for providing 5

minutes delays for capacitor feeder in closing circuit when capacitor switched OFF or

Tripped.

This relay should be instantaneous type with low voltage setting. Voltage setting value is

decided to 80% of normal voltage.

1.8.2 Over-Voltage protection:

Over voltage protection is provided for tripping capacitor bank when system voltage

exceeds the maximum permissible voltage i.e. 110% of the rated voltage. This relay

should be instantaneous type.

1.8.3 Neutral Displacement Protection:

This type of protection is required I case of a single star connected capacitor bank.

Primary winding of the Residual Voltage Transformer (RVT) is connected in Delta to

45

capacitor bank and the secondary winding of RVT is connected in open delta. Two

secondary terminals of RVT are wired up to NDR relay.

Under balanced condition of the capacitor bank, voltage across the open delta terminals is

almost Zero. But in event of failure of one or partial unit in a capacitor bank, neutral is

shifted and this is reflected on the open delta terminals. This unbalanced voltage value is

specified value depends on numbers of units in capacitor bank. A setting for NDR is

selected as 5 Volts for 1 Sec.

The modern Numerical relay does not require open delta voltage from RVT. But this

relay requires 3phase, 4wires voltage of Star connected secondary winding of RVT and

this relay derive Open Delta Voltage internally.

2.0 TESTING AND MAINTENACE OF PROTECTION RELAYS

Unlike other equipment, the protection relays remain without any operation until a fault

develops. For a reliable service and to ensure that the relay is always vigilant, proper

maintenance is must and must be carried out periodically.

2.1 MAINTENANCE TESTS:

Maintenance tests are done in field periodically. The performance of relay is ensured by

better maintenance. Basic requirement of sensitivity, selectivity, reliability and stability

can be satisfied by proper maintenance.

Due to operating conditions in substation, dirt and dust may accumulate on relays, relay

contacts. To avoid this relays are to be cleaned periodically.

Loose electrical connection can cause extra and may result in false operation of relay. To

avoid this, all the relay connections are to be tightened every now and then.

To confirm that relay operation at the particular setting under particular conditions for

which the relay is meant for operation, we should perform number of tests on relays

periodically (ROUTINE RELAY TESTING).

To confirm the breaker operation by closing of relay contacts by operating relay for

particular protection (THROUGH TESTING).

Secondary injection tests i.e. relay testing, tripping tests are to be carried out at least once

in a year.

46

2.2 SECONDARY CURRENT INJECTION TEST SET

Secondary current injection set is used to carry out secondary injection tests, is used to

inject current in CT secondary circuit to checks operation of relays and tripping of

breaker. It comprises calibrated variable current and voltage supplies and timer devices

which used for relay testing and obtaining their characteristics.

Secondary injection does not check overall system including CT‘s. It is rare occasion for

fault in CT, secondary test is sufficient for routine testing.

In System Protection Dept, there are 4 nos of 1 phase conventional type secondary

current injection set. There are 3nos(Doble – 1 no &Ponova – 2 nos) of laptop operated 3

phase secondary current injection sets with 3 phase current and 3 phase voltage outputs.

2.3 PRIMARY CURRENT INJECTION TEST SET

Protection relays is fed from a CT‘s secondary in the switchgear to be protected. Primary

current injection testing checks all parts of the protection circuit by injecting the test

current through primary circuit of CT‘s. Primary current injection set comprise current

supply unit, control unit and other accessories. Test set can give variable output current

47

by means of built-in auto transformer. Set is connected to AC single phase supply. The

output is connected to primary circuit of CT and can be varied by control unit of the set.

Using the primary current injection set, relay pickup and tripping of relays can be

checked. This test set is used for carrying out Stability tests for Restricted Earth Fault

(REF) test.

2.4 ROUTINE RELAY TESTING:

Steps to be followed in Routine Relay Testing

Cleaning of protection Relay, Auxiliary relays

All the connections from CT & PT end to relay terminals are to be tightened

Setting of relay is checked for assigned values and parameter as per testing sheet.

Testing of individual relay for each protection function

Through Testing from CT end to check relay operation for its each protection function.

Confirm tripping of breaker as per tripping scheme.

2.5 COMMISSIONING TESTS:

Commissioning tests are field tests to prove the performance of relays circuit in actual

service while carrying out new commissioning jobs and replacement jobs.

Steps to be followed in commissioning tests

Checking wiring on basis of the circuit diagram / drawing

Current Transformer (CT) testing for CT ratios, Polarity, Knee point voltage.

4.0 TRIPPING INVESTIGATION:

4.1 Whenever there is any tripping of Transformers and outgoing feeders in system reported

by O&M Departments. Such as Power Transformer tripping, feeder tripping, Power

Transformer tripping along with feeder tripping, tripping without relay indication,

tripping of feeder breaker for downward fault, etc. The tripping investigation is carried

out to ascertain the correct operation of protection relays, analysis of operation of relays,

type of fault in the system.

4.2 For carrying out tripping investigation, outage of transformer/feeder is taken.

4.3 Initially, we carry out through testing without disturbing protection system. Then relay

characteristic is verified by secondary current injection method. For proper co-ordination,

suitable action like increase/decrease TMS setting value etc. is done. For finding out the

cause of tripping, the necessary data such as SCADA report, fault report, fault event data

recorded in the relay and disturbance recorder data is analyzed. If setting is changed,

same is kept under observation.

4.4 The tripping investigation report is lodged in respective Controls and forwarded to

concerned O&M Department.

5.0 PROCEDURE IN RESPECT OF TESTING OF TAP-CHANGE CONTROL

RELAYS

5.1 General:

All Power Transformers installed in our Receiving Sub Stations are provided with on-

load tap-change gear i.e. the taps of transformer can be changed when the transformer is

on load. This tap change gear can be operated manually by checking or electrically by

remote control or automatic control.

5.2 All the automatic voltage regulating relays (AVR) are inspected for the correct operation

of OLTC. The automatic operation of tap-change control can be described as follows:

5.2.1 Automatic Voltage regulating relay, which is sensitive to change in voltages, is connected

across secondary side of Potential Transformer installed on 110kV side of Power

58

transformer. Whenever the Secondary voltage of Power Transformer increases or

decreases by 150 Volts, the secondary voltage of Potential Transformer will increase or

decrease by approx.1.5voltage (P.T. ratio 11000/110 Volts). This change in voltage starts

the voltage regulating relay which immediately gives impulse to a timing relay. If the

system voltage remains in this condition for more than 60 seconds, timer completes and

an electrical impulse is given to operate on load tap change gear (OLTC) to lower or raise

the tap to maintain voltage within permissible limit.

4.(b)(iv)) The norms set for discharge of functions

1) The monthly group incentive bonus scheme for the employees of the erstwhile Meters

and Relays Department working in the ‗Testing and Repairs Section‘ was in existence till

well as relays, punch clocks, other measuring instruments, minor gadgets, etc. under the

approved I.B. Scheme no. 51 for the group no. 518 & 519.

The purpose of implementation of this scheme was to improve efficiency at a minimum

cost and

i) To maintain reliability of operation and accuracy of performance of various types of

energy meters,

ii) Ensuring that the protective, indicating and regulating relays operate at the required

settings with proper indication,

iii) Ensuring that all protective and testing equipments that are procured complies with

the requirements of the specification.

Scheme No. 51

Group No. 518,519

Date: 01.04.2008 to 31.03.2010

GROUP INCENTIVE BONUS SCHEME NO. 51 FOR TESTING AND REPAIRS

SECTION OF THE METERS AND RELAYS DEPARTMENT

1. OBJECTIVES:

1.1 This monthly group incentive bonus scheme for the employees working in the ‗Testing and

Repairs Section ‗ of the Meters and Relays Department, who are carrying out the work of

overhauling and testing of meters as well as relays, punching clock, other measuring

instruments, minor gadgets, etc. is being introduced for the purpose of :

a) Providing an easy way to compute the performance level of each group by relating the

input manpower of the group with its work output.

b) Providing for incentive bonus payments which are related to the improved performance

level maintained by each group, during the month as envisaged under BCR 780 dated

24.10.1977.

1.2 In the end result, it is expected to increase the productivity of these sections by

encouraging greater co-ordinated effort, by reducing absenteeism, and by promoting

better participation by supervisory and other staff engaged in ancillary work and auxiliary

work.

1.3 Specifically, the scheme would achieve the following:-

1.3.1 Maintaining the reliability of operation and accuracy of performance of energy meters,

M.D. meters and Sine meters at a high standard, by proper periodic attention.

1.3.2 Ensuring that the protective, indicating and regulating relays operate at the required

settings with proper indication.

1.3.3 Ensuring that all protective and testing equipment that is procured complies with the

requirements of the specifications.

1.4 In short, the prime objective is to improve efficiency at minimum cost by the payment of

incentive bonus.

68

2. SCOPE:

2.1 This scheme covers two distinct and separate groups.

2.1.1 Group- ‗A‘

Group ‗A‘ comprises all tradesmen on direct work, indirect work, helpers, tradesmen on

ancillary and auxiliary work and unmeasured work, supervisors and Deputy Engineers

connected with the testing activities.

2.1.2 Group- ‗B‘

Group ‗B‘ comprises all tradesmen on direct work, indirect work, helpers, tradesmen on

ancillary and auxiliary work and unmeasured work, supervisors and Dy.Engineers

working connected with the activities of the Repairs Section and the Instrument Section.

2.1.3 In this scheme total 5 nos. of M.V.drivers who are working in Meters & Relays

Department are included.

3. ACTIVITES

3.1 The activities performed by these sections are listed in Appendix ‗I‘

4. DESIGN OF THE SCHEME :

4.1 Standard Time

4.1.1 Standard times in standard man minutes have been worked out based on : Work

measurement, analysis of past data and analytical estimating or major parts of activities in

the Testing Section and Repairs Section.

4.1.2 The standard times for the various activities carried out in the Testing Section and the

Repairs Section are shown in Appendix IIA and Appendix IIB respectively.

4.2 Allocation of manpower

4.2.1 Average expected monthly outputs for different activities of the groups are worked out

based on past data, modified for future needs and converted into standard man-minutes

(See Appendix IIIA and Appendix IIIB).

4.2.2 In addition to the quantified and measured activities, the section also perform

unmeasured activities. These are listed in Appendix IV.

69

4.2.3 Manning

4.2.3.1 The number of indirect workers required for a achieving the outputs referred at 4.2.1, is

calculated based on the sections working for 25days a month and 45.25hrs, a week.

Average performance level is assumed to be 135%(See Appendix VA and Appendix VB)

4.2.3.2 The allocation of manpower ( as direct and indirect) for, executing he measured as well

as the unmeasured work and the requirements for leave reserve at 15%, are also shown in

Appendix ‗V‘

4.2.3.3 Manning will be reviewed as and when necessity arises due to addition or reduction of

activities sustained changes in the composition of monthly outputs. Under these

circumstances, addition or reduction to the number of employees allocated on the

permanent basis will be on the recommendations of the Joint Work Study Committee and

the approval of Addl.GM(ES).

4.3 Computing Average Group Efficiency(AGE)

4.3.1 From the output from the various activities in the month, the total standard man-minutes

produced by each of the group will be calculated using the standard time for each

activity. The AGE for each of the group will then be calculated using the formula.

Total std man-min. produced by the group X 100

AGE = ---------------------------------------------------------------

452.5 X Total No. of direct worker days available

during the month

This formula for computing group efficiency is based on the output by the direct workers

in the group whose number is shown in Appendix VA and VB.

4.3.2 The Average Group Efficiency(AGE) shall be used for obtaining the Factor for Incentive

Bonus(GIB) which would be the percentage of basic salary payable as incentive bonus to

each member of the group, subject to other stipulation laid down in Appendix VA and

VB, Appendix VII and in clauses under section 6 relating to quality.

4.4 Payment of Incentive Bonus

The relationship between AGE and FIB is given in Appendix VI. These payments shall

be effected every month. For standard performance, i.e. 115% performance level (or

AGE) the amount of incentive payable is 18% of the basic salary and for 153%

performance level (or AGE) it is 45%. No Incentive Bonus is payable below 115%

performance level.

70

5. QUANTITY OF PRODUCTION

5.1 The Asst. Engineer or Superintendent with the help of the Dy. Engineer and the

supervisors, is expected to : schedule and plan the activities well in advance, ensure

availability of materials and special equipment for the activities planned, and co-ordinate

transport of men and materials. While every effort shall be made to maximize production,

standards of safety and quality shall be maintained.

6. QUALITY CHECKING

6.1 On Line Quality Checks

The Supervisor shall spot check the work of every Meter Tester once a day and if he

finds that the error is out of limits he shall direct the Meter Tester to repeat the test and

correct the meters which require adjustment.

For the above purpose, the test shall be ―Speed Test at U.P.F. and half load‖ and it shall

be carried out when the meters which require adjustment.

6.1.2 Final Quality Checks :

6.1.2.1 A ‗Dial Test‘ shall be performed on each and every tested meter on a separate bench as
