Generator Circuit-Breakers (GCB) vs. Conventional High-Voltage Circuit-Breakers: The Key Differences

A generator circuit-breaker (GCB) is the dedicated protective device installed between the generator and the step-up transformer. GCBs and conventional high-voltage circuit-breakers both rely on an arc-quenching medium to interrupt fault current, but the generator circuit is a different world: it
