Description :

ADR241B is second generation of Numerical

Over current IDMT/DMT 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 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

setting 18 Vdc – 250 Vdc.

The relay is having total 8 nos of dual LED of high

intensity for easy identification of type of fault for

easy user interface. LEDs L5, L6 and L7 and

Relay R1 to R6, digital status input and controlled

output are fully programmable via key pad

interface.

Main Functions : The ADR241B are having following protection

functions.

1. 4 stages of Phase Over Current element.

(Ip1>, Ip2>, 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. Trip Circuit Supervision.

5. Breaker Failure Detection.

6. Monitoring Functions.

7. Auto Recloser Relay (ARR).

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

Over Current element it can be programmed as

IDMT or Definite Time.
