Stator inter turns fault detection using discrete wavelet transform

The main objective of this paper presents a discrete wavelet transform (DWT) to diagnoses the stator inter-turns faults in three induction motor. This technique is based on the analysis of stator current under healthy and faulty states. Through the energy stored in each decomposition obtained by wavelet analysis, it was possible to remedy the problem of confusion between the types of defects above the short-circuit defect.
