Auto Synchronizing Panel

One of the most critical operations in any Power Systems is the paralleling of machines. Auto – Synchronizing Relay removes this function from the hands of the operator and/ or Semi – Automatic Permission relaying system and precisely places a machine on the line with no disturbance.

Auto synchronizing relay combines voltage and frequency matching with phase sensing and sequencing circuits to provide breaker closure at approximately zero phase angles with the aid of an anticipation function to offset the pre – selected breaker closure time.
