Presented in this paper is the development and analysis of deterioration predictors that may be used to detect electrical winding deterioration in induction motors. One major advantage of the approach that is described is that it may be used to reliably indicate low levels of deterioration in induction machine windings even though the machine may have internal construction unbalances and may be operating under conditions of varying applied voltage magnitude and symmetry. In addition, the proposed monitoring scheme is relatively simple in concept and may be implemented in practical situations. The procedure, and its robust nature, is illustrated by application to the detection of turn-to-turn deterioration in the stator winding of a three-phase induction motor.
