The stator inter-turn faults and stator electrical asymmetries such as stator resistance and inductance unbalance generate similar negative sequence current signatures in the induction machine. Hence the stator inter-turn fault is one of the most difficult faults to discriminate and detect in an induction machine. Discrimination of the stator inter-turn fault from stator electrical asymmetry essentially...
In previous works, the authors proposed a novel method for the diagnosis of rotor bar failures in induction machines, based on the analysis of the startup stator current through the discrete wavelet transform (DWT). In those works the physical basis of the method was described and several verifications were done in order to confirm its validity. These verifications were satisfactory, but they were...
