Abstract :
A technique has been developed whereby faults in 3 phase induction motors can be detected by an analysis of a single, no-load, starting transient. The system has been developed on laboratory test-rigs and validated via computer simulation and industrial testing. The basis of the technique is explained and simulation and test data presented. Possible areas of future application and development are discussed.
