Reyrolle solkor relay
Reyrolle solkor relay
(OP)
Guys, I would like to know if a Solkor relay can be used for transformer protection. I understand that the Solkor relay is used for zone protection but I came across 4 transformer feeders today that have Solkor relays connected to it. Thanks.

Im not shure, you have check manual.
If I remebare right, Solkor is only line differential, 87L, that means w/o option trafo protection in zone.
Best Regards.

From the old Reyrolle product range you would normally use a Duo-bias relay for transformer protection. The present-day Solkors were designed as high speed differential relays for line protection. I think the older Solkor types included busbar protection: the Solkor name goes back at least 50 years and probably longer.

It has abt 5 studs on the front(assuming that this is resistance settings) that add upto 490.
