A Study on Feature Extraction of Fault Signal for Stator Winding using Epoxy/Mica Coupler

에폭시/마이카 커플러를 이용한 고정자권선 결함신호 특징추출에 관한연구

In this Study, we have acquired 5-simulation Fault types Signals of high voltage Motor stator winding using epoxy/mica coupler. In order to know stator winding fault type using fault signals, we have performed feature extraction to apply wavelet transform technique. we have obtained skewness and kurtosis as statistical parameters of fault signal pattern from non deterioration state winding. We have know that 5 fault signals types have done an exponential function pattern shape but individually fault a class widely was different each other a signal waveform of pattern.
