Problem With REL 511

Sir

Please test the relay for both forward and reverse zones.

May be a problem with direction.

Raju.S

What were the commissioning results? Also I have found out problems may appear because of the communication system. I had some problems with autorecloser reactivation because of a SCADA system communication problem. More over, did you check the current and voltage transformers?

ABB.

thnx to all for helping.

but the relay did not make any trip neither forward nor reverse or over current.

and i checked the setting and configuration

and downloaded it from a healthy relay

and i did not need any communication to test the distance scheme

Sir

which kit u are using for testing?

do you expect any problem in the output relay u are selecting to trip the kit.

are u able to read current while testing from the relay.

Please check pt fail logic is preventing the trip

regards

raju
