Auto-Reclose and Check Synchronising
General Information
- Description
Automatic circuit reclosing is extensively applied to overhead line circuits where a high percentage of faults that occur are transient in nature. Automatic reclosing of the circuit breaker attempts to minimise the loss of supply to the customer and reduce the need for manual intervention.
Check synchronising ensures that a circuit breaker can only be closed when the voltages and frequency of the power system on each side of that circuit breaker are within acceptable limits.
