CB HEALTHY AND SYSTEM CHECK TIMERS

This logic provides signals to cancel Autoreclose if the circuit breaker is not healthy (for example low gas pressure)

or system check conditions are not satisfied (for example required line & bus voltage conditions) when the scheme

is ready to close the circuit breaker.

At the completion of a dead time, the logic starts an Autoreclose healthy timer. If a circuit breaker healthy signal

becomes high before the Autoreclose healthy time is complete, the timer stops and, if all other relevant circuit

breaker closing conditions are satisfied, the scheme issues a circuit breaker Autoclose signal. If the circuit breaker
