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 phase, E/F current and
PT Secondary voltage along with different
optical isolated status connections. The high-
speed micro-controller samples these current
and voltage signals through a A/D converter.
The Digital Signal performs powerful
Numerical Algorithms to find out RMS of
fundamental & harmonic contents of the current
and voltage, the direction of power flow then
this value is used for protection and metering
function. All measurement is tuned to
fundamental frequency i.e 50 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/DMT Over current protection,
Instantaneous Over current protection, Earth
Fault protection, IDMT/DMT Directional Over
Current and Earth Fault, Instantaneous
Directional Over Current and Earth Fault
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

for easy user interface. LEDs L5, L6 & L7,
digital status input and control output R1 to R6
are fully programmable via keypad interface
Main Functions The ADR245B are having following protection
functions.
1. 4 stage of Directional phase Over current
element. (Ip1>, Ip2>, Ip>> and Ip>>>).
2. 3 stages of Directional 3Io (Internally
derived EF) (3Io>, 3Io>> and 3Io>>>).
3. 3 stages of Directional Ie (Externally EF or
REF) (Ie>, Ie>> and Ie>>>).
4. Negative phase sequence element.
5. Under / over voltage Protection .
6. Neutral Displacement voltage Protection .
7. Trip Circuit Super vision.
8. Breaker Failure Detection.
9. Monitoring Functions.
10. Auto Recloser Relay (ARR).
11. Relay / LED configuration
Each of these functions are independently
programmable and can be enable or disable by
user depending upon requirement.
Over Current Element:
The ADR245B is member of Ashida Numerical
Relay family design for protection general
feeder. The relay has four independent stages
of directional 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 (Ip>) is separate and not
connected to trip contact. The output of Ip1>
and 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 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).
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 for stage 1 and stage 2 3Io
is 10% to 100% and for stage 3 3Io is 50% -
1200%. The Range for EF is from 5% to 80%
for stage 1, stage 2 and 50% to 1200% for
stage 3. The output of stage 1 (Ie>) is separate
and not connected to trip contact. The output of
> can be assigned to any of 6 programmable
relay through key board. While output of >> and
>>> is connected to trip element. Thus Ie> can

be used as ALARM before TRIP or can be used
to TRIP another CB before tripping main CB.
As standard practice all direction relay use two
healthy phase voltage for direction detection
and use MTA setting for phase angle
correction. For example R phase element use
R phase current and Y, B phase voltage. In
ADR245B use standard star connection at relay
side and internally reconstruct phase to phase
voltage required for direction detection.
Similarly relay calculates open delta voltage
(3Vo) and EF current (3Io) required for
detection of EF element.
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

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.
Trip Circuit Supervision:-
The ADR245B 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 or both
inactive.
i.e CB NO as will as CB NC are both close
or open. Relay detects any internal

(DT3) 4) Dead Time for shot 4 (DT4) and 5)
Reclaim Time (RT). After clearing of fault
ADR245B trigger dead Time 1 i.e DT1. after the
time delay Relay provide 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.
Breaker Failure Detection :-
Normally after tripping current should become
Zero within 100 – 200ms time depend upon
type of fault and breaker mechanism. After
Fault ADR245B 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. These
contacts is marked as Breaker Fail can be used
to TRIP back up breaker or can be used to
generate ALARM signal.
Under / Over Voltage Alarm :-
The ADR245B relay will be included
programmable function to detect under / over
voltage conditions. Relay had separate under
voltage and over voltage element. The under
voltage setting is from 45% to 95% and over
voltage setting from 105% to 155% of rated
(100% = 65.5V). Each function can be
separately enable or disable independently.
Whenever any phase voltage is above over
voltage setting or below under voltage setting
relay start internal timer (settable from 0.1 to 10
sec in steps of 0.1 sec). If voltage remain
abnormal during is time relay generate Alarm
signal. Any of the output element from RL1 to
RL6 can be assign to this function. The output
can be use for alarm or tripping of CB.
Negative sequence over current (46): - The ADR245B relay will be included
programmable function to detect unbalanced
fault conditions. When earth fault elements are
not operated or not sufficiently sensitive. The
ADR245B 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.
Neutral Displacement Voltage Protection :- Neutral displacement voltage protection function
is provided with internal & External selection.
With internal setting it uses 3Vo voltage (Open
Delta voltage) for sensing. In external setting it
uses external PT Voltage (Terminals C27 &
C28) for sensing. The setting is from 5.5V to
20V. Any output elements i.e. from RL1 to RL6
can be assign to this function.
