Generator/transformer circuit breaker
Generator/transformer circuit breaker
(OP)
We have a 415v 2Mva generator connected via a circuit breaker to a 415/6.6kv transformer. The complete unit is trailer-mounted. We intend to use it to temporarily supply some 6.6kv plant. What protection is required on the 6.6kv outgoing supply?

Would it be acceptable to fit a protection relay on the HV side, which trips the LV circuit breaker? i.e. no HV circuit breaker.

i just wonder how the generator will do with the transformer inrush...probably will just lower voltage a bit

A ground fault relay on the high side to trip the LV breaker would be a good idea, if the primary winding is to be grounded.
