Abstract

A method for operating a processing system to identify faults in an electric machine system including a multiphase machine having plurality of sets of windings; comprising: receiving parameter information representative of electrical operating parameters of the multiple phases of each of the multiple winding sets of the multiphase machine; determining symmetrical components based on the parameter information; comparing the symmetrical components to fault information defining faults of the multiple phases of the multiple winding sets with respect to symmetrical component fault values; identifying faults in one or more of the multiple phases of the multiple winding sets based on the comparison.
