A synchro-check panel, or synchro-check relay panel, is a component in electrical power systems that ensures safe and reliable connection of two power sources by verifying that they are synchronized before closing a circuit breaker. It monitors voltage magnitude, phase angle, and frequency differences between the two sources and only allows the breaker to close when these parameters are within acceptable limits. This prevents damaging surges and disturbances that can occur when connecting unsync
