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 or 60Hz
depending upon setting, thus relay remain stable
during distorted waveform by various industrial
load. 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 types of power
supply modules available 1) having range of
77Vdc – 250Vdc. Covering requirement of 110Vdc
and 220Vdc station battery system 2) Wide range

(Pre l iminary)
‚þ¹ªþ¸þ
ASHIDA Numerical 3OC + 1EF Protection Relay
Each of these functions are independently
programmable and can be enabled or disabled by
user depending upon the requirement.
Over Current Element :
The ADR241B is member of Ashida Numerical
Relay family design for protection general feeder.
The relay has three independent stages of Over
Current (Ip1>, Ip2>, 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 250% for Phase. The output of
stage 1 (Ip1>, Ip2>) is separate and not connected
to trip contact. The output of Ip1>, Ip2> can be
assigned to any of 6 programmable relay through
key board. While output of Ip>> and Ip>>> is
connected to trip element. Thus Ip1>, Ip2> 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).
Earth Fault Element :
The Relay has 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 stage 1 and stage 2 for
3Io is 10% to 100%, and for stage 3 of 3Io is 50%
to 1200%. The Range for EF is from 5% to 80%
for stage 1 and stage 2 and 50% to 1200% for
stage 3 The output of stage 1 (Ip1>, Ip2>) is
separate and not connected to trip contact. The
output of stage 1 can be assigned to any of 6
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.
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

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.
Trip circuit Supervision : The ADR241B is having 2 separate digital opto-
coupler status input which can be used to
continuously monitor the 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 is 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.
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
ADR241B 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 generates 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.
Breaker Failure Detection :
Normally after tripping, current should become
Zero within 100 – 1000ms in steps of 50ms time
depending 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 declares 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.
Negative sequence over current (46)
The ADR241B relay will be provided with
programmable function to detect Unbalanced Fault
conditions. When Earth Fault elements do not
operated or not sufficiently sensitive. The ADR241B
relay is included with Negative Phase Sequence
