3. HANDLING
3.1 RECEIPT OF RELAY
Care must be taken when unpacking & installing the relay so that none of part is damaged
inside the box. Operation manual and test report are there store this property for further use.
Relay must be handled by skilled personnel. Relays that have been removed from their boxes
should not be left in situation where they are exposed to dust or damp. This particularity
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.

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

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>

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.

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.

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.

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.
