Voltage selection relay
Voltage selection relay
(OP)
we have an application wherein under voltage load shedding scheme needs to select 3 phase voltage from one of possile three line VTs.Can some one suggest a voltage selection relay capable of accepting three sets of three phase voltages?

That menas 9 voltage inputs and few 3-ph/1-ph undervoltage protection function for every set.
I don't know such simple relay, only high class terminals, like to ABB REC670, but it's overkill, from my point of view. From other hand, its an load shedding, maybe you need some additional logic and load monitoring.
Please give more information.
Best Regards.

Also consider three voltage monitor relays and a smart relay.
