Synchrocheck Relay
Synchrocheck Relay
(OP)
Greetings
We have 13.8kV Ring Main Units (2 Ring C.Bs and 2 Tee-off C.Bs)feeding 13.8/0.48kV Transformers which feeds LV Switchgear with 2 incomers and a Bus-Tie configuration.
Since the incoming source for both the LV incomers is same (same RMU feeding both LV Incomers), so will there be any condition under which I will need a synchrocheck relay?
Thanks

I agree there should be a phasing process when it is first energized, event if you have three phase sync-check.
The problem with sync-check is if it is wired in reverse it will only allow you to close out of phase.
