applies to installation which are carried out at the same time as construction work. Relays that

are not immediately installed should be returned in to there corrugated box.

3.2 UNPACKING

Care must be taken when unpacking and installing the relays so that none of the parts is

damaged or the setting altered. Relays must only be handled by skilled personnel. The

installation should be done by clean, dry and reasonably free from dust and excessive

vibration. The site should be lit to facilitate inspection. Relays that have been removed from

their cases should not be left in situations where they are exposed to dust and damp. This

particularly applies to installation which are being carried out at the same time as construction

work

3.3 HANDLING OF ELECTRIC COMPONENTS

Electrostatic discharge (ESD)

As relay can be tested completely from external connections and relay setting can be done by

push button from front plate, there is no need to open the metal box.

The relay use component that are sensitive to electrostatic discharge. The electronic printed

circuit board (PCB) are well protected by the metal case. So unnecessary do not touch the

PCB tracks, connector, electronic component as they can be damaged by static electricity

discharge form the body as normal movement of a person can easily generate electrostatic

potentials of several thousand volts, discharge these voltage into ESD sensitive component

when handling electronic circuit can cause serious damage which often may not be

immediately apparent but the reliability of the circuit will have been reduced.

The electrostatic discharge when housed in the metal box do not expose them to risk of

damage by electrostatic discharge.



Page 4/6 3.4 STORAGE

If relays are not to be installed immediately upon receipt they should be stored in a place free from dust and moisture in their original cartons. Where de-humidifier crystals will be impaired if the bag has been exposed to ambient conditions and may be restored by gently heating the bag for about an hour, prior to replacing it in the carton Dust which collect on a carton may, on subsequent unpacking find its way into the relay, in damp conditions the carton and packing may become Impregnated with moisture and the de-humidifier will lose its efficiency. Storage temperature: -25°C to +70°C

3.5 DIMENSIONS

3.5.1 Connection of power terminals, and Signals terminals

The individual equipment are delivered with sufficient M4 screws to connect the relay via annular terminals, with a maximum recommended of two annular terminals per contact. To insure the insulation of the terminals and to respect the security and safety instructions, an isolated sleeve can be used. We recommend the following cable cross-sections: − Auxiliary sources Vaux : 1.5 mm² (some electrical utiliets use 2.5 mm2 ) − Communication Port – D9 Femel with 0.5 mm2 per core total 4 core screen. The maximum

length of 1000m. Linear capacitance between conductor and earth : 100pF/m − PT Circuit 1.5 mm2 − Other circuits 1.0 mm² − CT Circuit 4 - 6 mm2 We recommend to protect the auxiliary source connection by using a fuse of type NIT or TIA with a breaking capacity of 16A. For security reasons, do never install fuses in current Transformers circuits. The other circuits must be protected by fuses.

3.5.2 Earthing Each equipment must be connected to a local earth terminal by the intermediary of a M4 earth terminals. We recommend a wire of minimal section of 2,5 mm², connected to cabinet bolt . Because of the limitations of the annular terminals, NOTE : To prevent any electrolytic risk between copper conductor or brass conductor and the back plate of the equipment, it is necessary to take precautions to isolate them one from the other. This can be done in several ways, for example by inserting between the conductor and the case a plated nickel or insulated ring washer or by using a tin terminals.

6.4 Description:

ADR241B is second generation Numerical 3 OC + 1EF Over Current Relay. It consist all the

necessary protection and monitoring functions required for Normal feeder it consist of

1. High Speed Digital DSP Controller

2. Analog Measuring Module

3. Power supply Module

4. Digital Input output module.

The High speed Digital Signal Controller continuously monitors line phase current and E/F

current. Along with different status input, through CTs, and optical isolated status

connections. The high-speed micro-controller samples these current signals through a A/D converter. The Digital Signal performs powerful Numerical Algorithms to find out RMS of

fundamental & harmonic contents of the current. All measurement is tuned to fundamental

frequency i.e 50Hz, thus relay remain stable during distorted waveform generated

electronics loco-motive. All these measure values are then used for different protection

function such as IDMT Over current protection, Instantaneous Over current protection, E/F

protection etc. These measured values are also displayed on large 20 x 4 LCD display for

metering purpose. The DSC also monitors different digital input through optical isolator and

perform some monitoring function such trip circuit supervision, and control potential free

contact for control CB and generate ALARM and Tele-signalling.

The power supply module is basically DC – DC converted designed using modern PWM

based Switching mode technique to convert 110Vdc station battery supply to the 12V and

24Vdc low voltage supply for relay electronics and control circuit. It also provides necessary

isolation from station battery. There are two type of power supply modules are available 1)

having range of 77Vdc – 250Vdc. Covering requirement of 110Vdc and 220Vdc station

battery system 2) having range of 18Vdc to 52Vdc covering 24Vdc, 30Vdc, 48Vdc station

battery requirement.


fault for easy user interface. LEDs L5, L6 and L7 and Relay R1 to R5, digital status input and

controlled output are fully programmable via key pad interface.

7.1. Main Functions The ADR241B are having following protection functions.

1. 3 stage phase over current element. (Ip>,Ip>> and Ip>>>).

2. 3 stages of 3Io (internally derived EF) (3Io>, 3Io>> and 3Io>>>).

3. 3 stages of Ie (externally EF or REF) (Ie>, Ie>> and Ie>>>).

4. 2 stages of I2 (internally derived Negative Phase Sequence) (I2>> and I2>>>).

5. Trip Circuit Super vision.

6. Breaker Failure Detection.

7. Monitoring Functions.

8. Auto Recloser Relay (ARR).

9. Digital Input / Output Assignment

Each of these functions are independently programmable and can be enable or disable

by user depending upon requirement

7.2. Over Current Element:

The ADR241B is member of Ashida Numerical Relay family design for protection general

feeder. The relay has got three independent stages of over current (IP>, IP>>, & IP>>>).

Stage 1 (>) stage 2 (>>) can be programmed as IDMT or definite time. All major international

IDMT curves are available. Stage 3 (>>>) can be programmed instantaneous or define time.

Range of for stage 1 and 2 is 10% to 200% for phase and 10 to 200% for EF. For stage 3

phase 50% - 2000% The output of stage 1 (IP>) is separate and not connected to trip

contact. The output of Ip> can be assigned to any of 5 programmable relay through key

board. While output of IP>> and IP>>> is connected to trip element. Thus IP> can be used

as ALARM before trip or can be used to trip another CB before tripping main CB.

Although the curves tend towards infinite when the current approaches Is (general

threshold), the minimum guaranteed value of the operating current for all the curves with the

inverse time characteristic is 1.1Is (with a tolerance of ± 0.05Is).

7.3. Earth Fault Element:

The relay has got two different type of Earth Fault one is marked as 3Io and another is

marked as Ie. The 3Io is derived internally by software through phase current while Ie is

measured from external CT. Thus Ie can be used as Core Balance CT(CBCT) or Restricted

EF (REF). Each EF is having 3 stages (>, >>, & >>>). Stage 1 (>) stage 2 (>>) can be

programmed as IDMT or definite time. All major international IDMT curves are available.

Stage 3 (>>>) can be programmed instantaneous or define time. Range of for stage 1 and 2

is 10% to 200%, for stage 3 phase 50% - 2000%. The output of stage 1 (3Io>) is separate

and not connected to trip contact. The output of > can be assigned to any of 5 programmable

relay through key board. While output of >> and >>> is connected to trip element. Thus I>

can be used as ALARM before trip or can be used to trip another CB before tripping main

CB. The separate output contact allows to use each stage for independent function such as

stage 1 can be used for ALARM stage 2 for tripping or both can be use for tripping

independent CB. Each stage can enable or disable depend upon application.

7.4. Inverse Time Curves: -

The each stage thresholds for phase (earth) over current can be selected with an Inverse

Definite Minimum Time (IDMT) characteristic. The time delay is calculated with a

mathematical formula

7.5. Trip circuit Supervision :-

The ADR241B is having 2 separate digital opto-coupler status input which can be used to

continuously monitor continuity of trip-circuit. The general scheme is as shown in fig. 4.

Relay monitor Trip coil continuity through CB NO during close condition and through CB NC

during Trip condition. If any discontinuity observed it generate Alarm signal.

The output marked as PROTH (Protection healthy) is normally is ON and become OFF at

following condition

When DC supply is not sufficient (DC fail)

When T1 and T2 both active and both inactive. i.e CB NO as will as CB NC are both

close or open. Relay detects any internal hard ware Error.

7.6. Auto Recloser Logic:- The ADR241B is provided with 4 shot auto recloser function. There are 5 timer for auto

recloser 1) Dead Time for shot 1 (DT1) 2) Dead Time for shot 2 (DT2) 3) Dead Time for shot

3 (DT3) 4) Dead Time for shot 4 (DT4) and 5) Reclaim Time (RT). After clearing of fault

AD241B trigger dead Time 1 i.e DT1. After the time delay Relay provides reclose command

and start reclaim timer RT. If second fault occur during RT relay trigger Dead Time 2 i.e DT2.

If third fault occur during RT relay trigger Dead Time 3 i.e DT3, If Fourth fault occur during

RT relay trigger Dead Time 4 i.e DT4 and after time delay it again provide reclose command

and retrigger RT. If fifth fault occur during RT Relay generate Lock-Out alarm and block

further reclose. The Lock-Out condition can be reset locally as well remotely by SCADA

through communication digital status input.

7.7. Breaker Failure Detection:-

Normally after tripping current should become Zero within 100 – 200ms time depend upon

type of fault and breaker mechanism. After Fault ADR241B trigger internal timer (settable

from 0.1s to 1.0s) If fault is not cleared during this time then relay declare as Breaker fail

(LBB function) and change another contacts. This contact is marked as Breaker Fail can be

used to trip back up breaker or can be used to generate ALARM signal.

7.8. Negative sequence over current (46)

The ADR241B relay will be included programmable function to detect unbalanced fault

conditions. When earth fault elements are not operated or not sufficiently sensitive. The

ADR241B include negative phase sequence over current element it can be programmed as

IDMT or definite time the actual setting range will be finalized during later stage of design

7.9. Programmable DI/DO and LED :-

The ADR241B has got 5 digital outputs, 5 opto-isolated input and 6 general purpose LEDs.

These can be programmed by local key board. Any logical of physical status can be assigned

to any relay contact.

7.10. Monitoring Functions (Event, Disturbance Record) :-

Apart from basic protection functions. Relay is continuously monitors all substations

operation through status, it internal functions, internal hardware etc. if any changed is

observed it marked as event. Such type of events is stored in internal non-volatile memory

along with time stamped. Following some of the events. Relay PKP, Relay Reset, CB Trip,

CB close, changed of any digital status input, Relay setting changed etc.

Up to 100 such event can be stored and can be download for detailed analysis. Apart from

Event record Relay also record actual waveform of current along with all digital and logical

status during fault condition. Up to 20 such waveforms can be recorded; the duration of

disturbance record is 1 sec. This waveform can be downloaded through communication port

for further analysis.

Rx+ and Rx- are Input to relayTx+ and Tx- are output from relay

8.3 Initialization

A reset of the communication function is affected by means of a reset command from the

control system. This is generally transmitted by control system when:

• Control system is initialized;

• The protection does not respond during a certain period. The reset command can be transmitted as:

• Reset frame count bit (FCB), or

• Reset communication unit (CU).

Reset CU will clear any unsent message frames in the relay’s transmit buffer.

The relay will respond to the reset command with an identification message ASDU 5, the

Cause of Transmission COT of this response will be either Reset CU or Reset FCB

Depending on the nature of the reset command. The following information will be contained in

the data section of this ASDU.

Manufacturer Name: ASHIDA

The Software Identification Section will contain the first four characters of the relay model

number to identify the type of relay.

In addition to the above identification message, if the relay has been powered up it will also

produce a power up event.



Page 5/9

8.4 Time synchronization

If the time synchronization message is sent as a send/confirm message then the relay will

respond with a confirm. Whether the time synchronization message is sent as a send confirm

or a broadcast (send/no reply) message, a time synchronization message will be returned as

Class 1 data.

8.5 General interrogation

In the control direction, general interrogation (GI) initiated by means of a GI command.

It is used to read the status of the relay, the function numbers, information numbers and

common address offsets that will be returned during the GI cycle.

When the list of messages subject to GI has been processed following by a GI command,

A GI termination message is then transmitted. A new cycle is not initiated in protection

equipment until a new GI impulse is received from control equipment.

8.6 Cyclic measurements

The relay will produce measured values using ASDU 3 and ASDU 9 alternately on a cyclical

basis, these can be read from the relay using a Class 2 poll. The measurands transmitted by

the relay are sent as a proportion of 1.2 times the rated value of the analogue value.

8.7 Disturbance records

The disturbance records stored by the relay can be extracted using the mechanism defined in

the IEC60870-5-103 standard. Disturbance data transmission initiated, first binary values are

transmitted first, followed by disturbance values. Initial status of the binary values transmitted

first, followed by tags for changed values.

Disturbance values are transmitted with increasing channel numbers. All ASDUs are

transmitted as data class 1 in the link layer.

9.1. INSTALLATION 9.1.1. Relay Connection and Diagram

Before installation of the relay check the correct working procedure as to ensure safety and

the equipment documentation. Terminal exposed during installation may present a hazardous

voltage unless the equipment is electrically isolated. Any disassembly of the equipment may

expose parts at hazardous voltage. Electronic parts may be damaged if suitable electrostatic

discharge (ESD) precautions are not taken. Voltage and current connection should be made

using insulated crimp termination to ensure that terminal block insulation requirement are

maintained for safety. To ensure that wires are correctly terminated the correct crimp terminal

and tool for wire size should be used. The equipment must be connected in accordance with

the appropriate connection diagram.

9.1.2. Before energising following should be checked

a. Voltage rating and polarity.

b. CT circuit rating and integrity of connection.

c. Protective fuse rating.

d. Integrity of the earthing connection.

e. Voltage and current rating of external wiring, applicable to the application.

9.1.3. Relay Operating Condition

The equipment should be operated within the specified electrical and environmental limits. 9.1.4. Current Transformer Circuit

Do not open the secondary circuit of a live CT since the high voltage produce may be lethal to

personnel and could damage insulation. Generally, for safety, the secondary of the line CT

must be shorted before opening any connection to it. For ADR241_V2, terminal block for

current transformer termination has automatic CT shorting on removal of the module.

Therefore external shorting of the CTs may not be required.

9.1.5. Insulation and dielectric strength testing

Insulation testing may leave capacitors charged up to a hazardous voltage. At the end of each

part of the test, the voltage should be gradually reduced to zero, to discharge capacitors,

since this may result in damage.

9.2.4. Final Checking

After completion of all relay functionality testing and relay setting check. Remove all tests as

temporary shorting leads etc. if it is necessary to disconnect any of the external wiring from

the relay in order to perform the wiring verification test. It should be ensured with the CT

connection are replaced in accordance with the relevant external connection or schemes

diagram. Ensure all fault & Annunciation contacts, trip contacts has been reset before leaving

relay.

If relay ADR241B_V2 is a newly installed or the CB has been just maintained the trip counter

of relay should be zero. This counter can be reset by using HW reset,LED reset and Up arrow

key.

After successful installation conformer amount of existing load current in each phase (R, Y, B)

and Earth Fault (3Io). This can be confirmed with Analog/ Digital current meter available on

panel with relay primary and secondary current measurement window. In normal Balance

load condition the 3Io current should be vey low. Similarly Positive sequence current I1

should be approximately equal to average value of phase current while negative phase

sequence current should be very low. Trip test also can be carried out with test push button to

confirm trip circuit this test can be conducted without load also.

9.4 Testing of Relay 9.4.1 Relay Calibration

Before conducting actual test confirm relay calibration by following method. • Connect ADR 241B_V2 relay to current injector and timer as shown in diagram.

• Following chart shows terminal numbers of 1A / 5A CT connections.

Phase 1A 5A R C3, C4 C5, C6 Y C7, C8 C9, C10 B C11, C12 C13, C14

EF C15, C16 C17, C18

• Connect R CT terminals as per the chart.



Page 11/24

• Adjust rated CT Secondary Current 1A/5A. Observe the current value from measurement

menu. The actual current should match with relay display.

• Adjust trimpot if it shows difference in actual and standard source. Refer following table

for calibration.

10.3.4. TESTING OF EARTH FAULT CURRENT PROTECTION 10.3.4.1. Testing of 3Io element

Note: The 3Io is internally derived zero sequence current from phase current. Before

testing of pick up timing check calibration from by giving known current from

stable current source for correct phase sequence and equal value. We recommend digital current sources such as Doble F610 or Omricon test set. Adjust current

equal to rated input, i.e. 1A for A input or 5A for 5A input. If all sources are same and equal then observed 3Io, I1 and I2 current display on relay measurement menu.

The 3Io value should be less than 0.05 , I1 = 1.0 or 5.0A (+/- 3%) depend upon relay 1/5A setting and actual current input. and I2 should be less then 0.05.

1. Connect to R Phase CT input terminal of ADR 241B_V2 relay to current injector and timer as shown in diagram.
