Q-208-098C 1. Outline This equipment is automatic synchronizing equipment used in the case of synchronous generation running with the system in parallel. On the occasion of parallel running，there is the need of smooth synchronous closing that suppresses the in-rushing current， alleviates the turbulence of the system and the shock to the generator by coinciding the voltage and frequency of both sides and by closing the circuit breaker precisely at the synchronizing point. -
