Motor Reclosing and Bus Transfer

Until recently motor reclosing problems were thought to be strictly academic exercises. With the testing that has been going on in the motor manufacturing industry and in the utility industry. this problem manifets itself as a real one and one that must be considered during system design. There is mounting evidence to support the fact that reclosing out of phase has damaged many a motor. This damage was usually thought to have been caused by operator error or poor design.
