ADR241S is second generation of Numerical Self Power Over current IDMT/DMT

Relay. It consist all the necessary protection and monitoring functions required for

compact RMU. 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



Page: 7 of 68


Rev.: 06 Dt. 10.01.2013

these current signals through 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 16 x 2 LCD display for metering purpose. The power supply module is

special electronics circuit which derived relay power from current flowing through

line; no any external power supply is needed. The minimum requirement of current

to build power supply for relay electronics is 20% in any one of the phases or 12%

in any 2 phases or 8% in all three phases. Relay provides pulse output to trip

RMU or compact CB having low energy tripping coil.

A battery for feeding the LCD display and SCADA communication buffers the

relay. After tripping operation relay maintains fault indication on LCD display.

During this time, the relay uses power through internal battery. The relay can

maintain fault indication till the relay is manually reset by using ‘+ /’ key. Failure

of the battery has no effect on the protection function of the relay. The battery has

a service life of more than 5 years.

3.0 Protection Function: -

3.1 Over Current / Earth Fault Protection: -

The relay has inverse time over current / earth fault function as well as

instantaneous protection for both. Following is summary of different protection

functions provided by relay.

ANSI IEC Protection Function

50 I >> Instantaneous Over Current Protection.

50N IE >> Instantaneous Earth Fault Protection.

51 I>T, Ip Time Over Current Protection (Phase).

51N IE >t, IEP Time Over Current Protection (Earth).

The relay has 4 sensing elements 3 O/C and 1 E/F. The tripping current can be

set to 20% -240% in steps of 1% for phase and 10% - 100% in steps of 1% for

earth fault by keyboard provided on front panel. These settings are available on

display. The unit has selection of IDMT characteristic of IEC standard Normally



Page: 8 of 68


Rev.: 06 Dt. 10.01.2013

Inverse1 (C1), Normally Inverse2 (C2), Very Inverse (C3), Extremely Inverse (C4),

Long Time Inverse (C5) and defines time (C6). The unit also has ‘Time Multiplier

Setting’ (TMS) from x0.01 to x1.2 in steps of x0.01 (separate for phase and EF) for

IDMT delay multiplication. Separate operating curve can be programmed for

phase and EF. The instantaneous tripping function has range of 50% - 3200% in

steps of 50% for phase and 50% - 1200% in steps of 50% for earth fault. The high

speed CPU continuously monitors all four current inputs and compares with IDMT

as well as instantaneous setting. If anyone current is above instantaneous setting,

the relay provides immediate trip command bypassing IDMT delay.

If input current is less than instantaneous setting but more than IDMT setting, CPU

calculates IDMT delay as per selected IDMT characteristic, multiplies it with TMS

setting and issue trip command if fault is persist even after this time delay.

For EF tripping, there must be current greater than or equal to 20% of the rated

current in any one phase of the relay.

3.2 3 Phase Over Load Function: -

The relay is having the overload function for the phases. The setting range for the

3 phase overload is 10 – 200 % in steps of 1% and the time delay is settable form

1s to 30000 secs in steps of 1 sec.

Please note: relay will operates on 10% only when the current flowing through all

the 3 CTs is around 7-8 % of the rated.

Following are some of the cases where we can use the overload function:

When connected distribution transformer is of very low KVA rating:

For example:

Transformer Rating: 100KVA

Transformer Voltage: 11 / 0.440 KV

Rated load at 11KV side: 5A

Connected C.T. Ratio: 40/1 A

As the rated load is very low i.e. 12% of the CT and the setting for IDMT over

current is available from 20%, so we can set the overload setting for 10% and the

time delay at the required value i.e. from 1s to 30000 secs and the IDMT setting at

require value. Hence we can able trip the transformer by using overload function

after desired set time.



Page: 9 of 68


Rev.: 06 Dt. 10.01.2013

When connected distribution transformer is of normal KVA rating:

For example:

Transformer Rating: 1000KVA

Transformer Voltage: 11 / 0.440 KV

Rated load at 11KV side: 52A

Connected C.T. Ratio: 80/1 A

In above case the rated load is 65%, so we can set the overload setting at 65%

and the time delay for the overload at require value between 1s to 30000secs. The

IDMT over current setting can be set at 70% and the IDMT delay as per the

requirement.

Thus we can allow the overload of 65% for the allowable time and if the overload

persists after the set overload time the transformer will get tripped with the

overload. The normal IDMT over current & EF protection can be taken care By

Ip>, IE> & the IDMT settings.

3.3 Cold load pick-up Function:

The relay is having special cold load pick-up function to avoid tripping due to

prolong inrush current. The setting range is given same as the normal protection

setting with additional cold load time delay settable from 0.01 to 10.0 secs.

Cold load pick-up function can use to avoid tripping during switching ON C.B. and

position of C.B. can be watched by connecting its auxiliary contact “C.B. NO” to

dedicated Digital input S1 of Relay.

As per observation normally in distribution system and as per gradation

Instantaneous setting and Ip> TMS required to set very low and due to this relay

can operate during switching on C.B.

In ADR241S Instantaneous elements have inrush blocking function during

switching on condition of CB but relay can operate in IDMT if inrush current flow

for sufficient time to operate relay as per TMS setting.

To avoid such condition Cold Load Pick-up can use in which we can set cold load

setting higher than regular protection setting for selected definite time delay “Cold

Load Timer”. As Clod Load Timer is finish relay will switch over to normal

Protection Setting.

If we are switching C.B. on fault condition relay will still provide protection as it can



Page: 10 of 68


Rev.: 06 Dt. 10.01.2013

operate when fault current is more than cold load setting and same can be

identified as in fault history “CLT” trip will appear in SF (status flag).

Following are some examples for getting the idea of cold load pick-up:

Relay ADR241S is connected with RMU on 11KV system with following setting

and Digital input S1 wired up with CB-NO.

Case 1: (Current peak is high in amplitude and small in duration) Inrush current

peak is 9 times of the rated CT for the duration of 0.5 s in R, Y & B

With above setting as CB switch ON the S1 digital input will also in ON

condition, cold load setting will comes in picture for selected delay 0.5 Sec.

As our peak current is 9A, the instantaneous element will not operate (as per

the setting it is set at 10A).

As per the over current setting in cold load Ip> = 100% & Ip> TMS = 0.15,

Operating time will be as per the Formula:

T= (0.14*0.15)/ ((9^0.02)-1)

= 0.467 Sec.

As peak current is for 0.5 Sec. and the calculated time in cold load is 0.4675s

relay will operate in Cold Load. In such case we have to increase the TMS

setting in cold load.



Page: 11 of 68


Rev.: 06 Dt. 10.01.2013

Case 2: (Current peak is high in amplitude and high in duration) Inrush current

peak is 7 times of the rated CT for the duration of 0.6 s in R, Y & B.

As our peak current is 7A, the instantaneous element will not operate (as per

the setting it is set at 10A) in this case also.



T= (0.14*0.15)/ ((7^0.02)-1)

= 0.529 Sec.

As per the above calculation of IDMT delay of the cold load settings the

calculated delay is less than the duration of peak current ,but the set cold load

delay is set at 0.5s (Less than the calculated delay) the relay will not operate

with cold load. After 0.5s it will switch to the Protection Settings. The operating

time as per IDMT for the protection setting will be:

T= (0.14*0.05)/ ((7^0.02)-1)

= 0.176 Sec.

By adding the above calculated delay in the cold load delay the operating time

will be: 0.5s + 0.176s = 0.676s (This is more than the peak duration). But the

Ip>> setting is 300 %( less than the current peak) and the IP>> Delay is 0.05s,

the relay will operate with HF in protection settings within 50 ms time delay (as

the peak duration is more than the calculated time i.e. 0.5s + 0.05s = 0.55s). In

such case we will have to increase the cold load delay.

Case 3: (Current peak is low in amplitude and high in duration) Inrush current

peak is 2.2 times of the rated CT for the duration of 1 s in R, Y & B.

As our peak current is 2.2A, the instantaneous element will not operate (as per

the setting it is set at 10A) in this case also.



T= (0.14*0.15)/ ((2.2^0.02)-1)

= 1.321 Sec.

As per the above calculation of IDMT delay in the cold load settings the

calculated delay is more than the duration of peak current ,but the set cold load

delay is set at 0.5s (less than the calculated delay) the relay will not operate

with cold load. After 0.5s it will switch to the Relay Settings. The operating time



Page: 12 of 68


Rev.: 06 Dt. 10.01.2013

for the protection setting will be:

T= (0.14*0.05)/ ((2.2^0.02)-1)

= 0.440 Sec.

By adding the above calculated delay in the cold load delay the total operating

time will be: 0.5s + 0.440s = 0.940s (This is less than the peak duration). Due to

this the relay will operate with protection setting. In this case we have to increase

the cold load timer or I>p TMS in the protection setting.

4.0 Measurements and Communication Function: -

In normal condition the relay displays all the current values. Using the front

keyboard the display can be programmed to show settings. If current is in fault

range the relay gives trip command. The type of the fault is displayed on LCD

display. During the fault condition, the relay measures the fault current and stores

it in non-volatile memory. The fault current can be read using keyboard on LCD

display. All settings can be done locally as well as remotely via communication

port and saved in non-volatile memory.

5.0 Impulse Output for Tripping Coil: -

Low Energy tripping coil of the circuit breaker can be connected to the coil terminal

marked as (COIL + and –) at back terminal. The trip energy (12 - 24 V DC 0.1

W/sec) is provided by a capacitor in the protection relay. Length of the trip impulse

is 40ms and pause between the individual pulses depends on the impedance of

the tripping coil and the current level. Pulsing is continued until the CB operates

and fault current become zero.

6.0 Supervisory Function: -

The relay continuously keeps track on its internal hardware and the moment it

detects any failure of component, a message is displayed on LCD display. The

type of error can be checked by “Error Log” menu. This feature is very useful for

giving pre information to avoid mal operation.

7.0 Electrical Noise Immunity: -

Utility and industrial environments are electrically very noisy. Electronics protection

equipment requires careful design and testing to ensure reliable operation in

switchgear. Ashida has applied its expertise and more than 35 years of experience

in field of electronics design to ensure that the ADR241S operates when required,

without nuisance trips. Thanks to the latest micro-controller technology.

Rev.: 06 Dt. 10.01.2013

8.0 Inrush Blocking:

During switching of load the load take sudden surge of magnetising inrush current.

The ordinary protection may sense this current as fault current and give wrong

tripping. The ADR241S relay has a special feature of inrush current blocking. The

relay detects inrush current then block instantaneous element tripping accordingly.

9.0 Current transformers Requirement: -

The ADR241S relay is self power numerical relay and derived all power required

for it internal operation as well as for it CB operation is derived from external CT.

The proper operation it necessary to select proper rated CT.

The Impedance to current characteristic of ADR241S is as shown in fig. The graph

is non linear, i.e. at low current Z of CT input is high while at high current it low.



Page: 14 of 68


Rev.: 06 Dt. 10.01.2013

From impedance Graph of ADR241S, the maximum Voltage required

across the relay terminal at fault current of 20 times of rated:

The Impedance value at 20 Times is 0.62 Ohm

Thus Voltage required is

V Max. = 0.62 x 20 = 12.4V

VA Min. required for external CT is

VA = V max X Safety Factor

Over Load Factor of CT

Considering Safety Factor 2 for Lead resistance / Connecting Impedance Etc.

VA = 12.4 x 2

20

= 24.8

20

= 1.24 VA for CT Class 5P20

= 2.48 VA for CT class 5P10

This is minimum VA required.

The recommended current transformers (CT) are as follows.

The actual CT design will be carried out by considering the site condition, Transformer capacity, required V max. For the relay and fault level. User should follow necessary design practice.

10.0 Setting Reliability: -

Any numerical or digital relay in which all settings are programmable via key board

or communication port, use some internal memory to store these settings. Many

relays use internal rechargeable batteries to maintain these settings. In case of

power supply fluctuation, batteries are often unreliable, and settings get corrupted.

In such situation, the relay may mal- operate. Ashida use special non-volatile

memory technology, which do not require any power source to maintain settings of

the relay.

Once the relay is programmed, it maintains the settings for more than 10 years

even in the absence of any power supply. In case if internal fault is detected in this

section during the self diagnosis, then relay gives message. 11.0 On Line Testing: -

The ADR241S relays are provided with online testing facility. By pressing TEST

key (provided on front panel) the relay immediately provides trip command. This

trip command also gets extended to breaker coil, thus entire trip operation from

relay to circuit breaker can be checked. This trip command is recorded as “T” flag

on LCD display as shown below.

I>> : t :0002

I> : SF : T

If the CB (circuit breaker) operation is un-desirable then, pressing BYPASS key,

the relay trip command can be blocked from extending to CB coil.

(Note: - This “Trip Test" function can be enabled through General Settings.) 11.1 On Line Testing by using Test Block.

The Relay is supplied with optional online Testing assignment i.e. Relay is

provided with D15 type connector at the backside of relay for connection of Relay

Testing Unit (TEST BLOCK). By connecting the Test Block via 15-pin cable all the

functions of the relay can be checked in service. While testing, the Trip contact

can be isolated by trip bypass switch on Test Block to avoid any type of tripping

operation. The current injector and the Timer can be connected to relay and entire

verification of the relay can be done.

14.0 Battery Function: -

Battery Specification: Capacity 4.5Volt (1.5 x 3) AAA Lithium non-rechargeable

battery, Make Panasonic, Energizer, or equivalent.

The ADR241S relay is Self Power relay, it takes power from CT Current for its

operation, after the tripping operation and when no current is available to view the

Fault Current in the different Phases of the relay, Relay takes power from Battery.

When there is no CT Current press “BAT ON” Key to view Fault current. When

“BAT ON” Key is pressed relay will remain ON for 1 Minute and after 1 Minute

relay becomes OFF to save the battery life, but if before completion of 1 Minute

any of the key (Excluding the HW Reset and the Bypass key) is being pressed it

will retriggered for 1 Minute time slab again. When the CT current is at 20% the

relay gets activated. Battery is located in the battery box on the Front Plate and

can be easily replaced by opening the cover.

Conditions of the relay getting switchover momentarily on battery are as

follows.

1. If the relay is in ON Condition and current drops below 10%.

2. When the current exceeds to settings i.e. pkp condition but not tripped and

drops below 10%.

Condition of relay getting switchover on battery for 10 Seconds is as

follows.

1. When relay gets tripped and current becomes Zero.

Note: -

1. The relay uses battery only for indication purpose. Battery is not required for

protection purpose.

2. AAA Lithium (1.5V x 3) non-rechargeable batteries are placed in Battery

Socket as shown below.

phase to phase fault).

OL: indicates the faults due to over Load I> Indicates TYPE of IDMT fault (e.g. RE for phase to Earth fault, RY for phase

to phase fault).

SF indicates Status Flag. When there is non- fault trip such as trip due to TEST

push button or Remote trip etc. it is displayed at SF

Following are the status fault and there meanings:-

T : Trip due to TEST push button.

R : Trip due to Remote Trip.

CLT: Tripped with cold load setting.

But if in General settings, Trip block is set YES it will display ‘B’ at SF to indicate

that tripping is blocked as follows

SF : B ( For IDMT or HF Fault Trip).

SF : TB (Trip due to Test push button)

SF : RB ( Trip due to Remote Trip)

SF : CLT ( Trip due to Cold Load)

37.0 Troubleshooting Guide line:-

Relay is not getting powered up / no display on relay / display is not working :

Check the current flowing from the CT, it should be more than 20% of rated in any one phases or more than 12 % in any two phases or more than 8% in all the phases.

Relay is not getting powered up on battery :

1. Confirm that batteries are properly placed in battery socket.

2. Check the voltage of the batteries with digital multimeter; it should be more than 3.2 V. If the batteries are proper and unused then it will be 4.5V.

Relay is not getting powered up at all (on load current nor on battery) :

Check all the above points and if all the things are ok but still it is not getting ON then contact ASHIDA for the further rectification.

Trip not working / relay is not tripping :

1. Check the connections of tripping coil. 2. Check the TRIP BLOCK setting in General Settings Menu (for details please

refer Chapter No. 17 in this manual), Trip block should be in disable mode.

Latching type relay contacts are not working :

Check the External Relay Enable/disable settings in General Settings Menu (for details refer chapter no 17.14). To operate the relay contacts External relay should be in enable mode.

Relay Tripping with 3Ph overload :

1. Check the settings of 3Ph Overload & OL delay (refer Chapter No. 19). 2. If you want to bypass the 3ph overload function, set the 3ph overload setting

and 3ph OL delay at maximum position i.e. 200% & 30000s respectively.

Cold load trip function is not working properly :

1. Ensure that the CB NO contact is properly wired up at the CB NO status input.

2. Check the settings of cold load (Refer chapter 3.3 and 21 for details).

Display showing error code 016 :

Set the date and time of the relay in general Settings Menu as per the current date & time (refer Chapter no 17 in this Manual).

In case of any further difficulties, please mail us the on [email protected] or contact us on +91-22-25822830 / 25823482.

Required details for launching a complaint:

1. Relay Type 2. Sr. No. of the relay (written inside the battery door of front fascia). 3. Details of the concern person (Name & contact number etc.) to whom our

support team can co-ordinate to resolve the issue.
