Synchronizing Current

Author: E.E. Kimberly

After the synchronizing switch in Fig. 20-8 has been closed at the proper instant, the drifting of alternator (a) does not instantly cease but continues until the resultant voltages E1aE1bj E2aEzb, and E3aE3b become large enough to enable the motorizing current circulating between the alternators to hold them exactly in synchronism. This current is called synchronizing current. If the prime mover driving alternator (a) were then disconnected, the synchronizing current would rise just enough to drive machine (a) as a synchronous motor.
