Breaker closing time - Westinghouse 50-DHP-250?
(OP)
I am trying to come up with an estimate of breaker closing time for the subject metal-clad switchgear breaker (5kV)in order to set up an auto synchronizer.
If anyone has access to an old installation manual or spec sheet for these breakers, and can find this data, I'd be very appreciative.
I'm guessing about 80 milliseconds, but it's really a guess.
