generator circuit breaker.
hello all,
i am working on a power plant project and we need to integrate a generator circuit breaker GCB.
this GCB is located between the generator and step-up transformer.
is it obligatory that The Generator Circuit Breaker shall be provided with capacitors on the generator side and transformer side ?
or a capacitor installed on transformer side only, no capacitor installed on the generator side?
thank you in advance

The transients that the capacitors are intended to snub out will come from the system, through the transformer. So snubber caps on the transformer side are beneficial to both the breaker and the generator while snubbers on the generator side benefit only the generator.
