The Synchro-Check Relay checks the synchronism between two independent ac power sources (a synchronous
generator and an ac power bus, for instance) and indicates when the two sources are synchronized (within
predetermined limits). This relay can be used to control the interconnection of two ac power sources to prevent
damages or disturbances in power systems. A synchronizing limit adjustment and two pairs of contacts are
provided.
