Detection of Stator Interturn Fault Using Discrete Wavelet Transform

Abstract

Induction motors are widely used in industries as they are robust and rugged in construction. Hence, it becomes necessary to have sophisticated technique for online detection of faults in Induction motor. In this paper author has presented a technique for stator inter turn fault detection using discrete wavelet transform. The proposed technique is implemented in MATLAB. The proposed technique compares the current in healthy and faulty condition to produce accurate results. The proposed technique uses discrete Fourier transform for signal processing and produces more accurate results as compared to traditional waveform analysis technique.
