Faults Detection Using Stator Current Monitoring of Induction Motor Electric Drives
free download
OA Syggeridou, M Ioannides ,Proceedings 4th International ,demosthenes.ece.ntua.gr A small amount of voltage unbalance will cause an increase in the winding temperature by an excessive amount. The overheating of the stator winding will lead to some stator winding faults, such as the turn-to-turn fault . A turn-to-turn fault is one of the more difficult
