training for CB circuit breaker

These schemes use the circuit breaker's 52b status contact because a generator's steady state contribution to a fault may be less than the recommended fault detector settings. In fact, circuit breaker (CB) contacts may be used whenever the expected current during a BF condition is less than the recommended fault detector setting.
