PCS-9659 Synchronizer
  • PCS-9659 is a digital synchronizer that determines the proper time to initiate closing of the circuit breaker to parallel a generator and bus, or to reclose a line. In order to fulfill different application requirements, it offers three synchronizing modes: automatic synchronizing, semi-automatic synchronizing and manual synchronizing. By monitoring frequency, voltage and phase angle, the PCS-9659 provides correction signals to the governor of prime mover and voltage regulator of generator for voltage matching and frequency matching.
