Abstract In this paper, As the wavelet transform has the properties of multi-resolution analysis and timefrequency domain localization, application of wavelet transform is used at partial discharge(PD) signal detected by electrical detection method to extract PD signal"s various frequency component and its time domain. therefore we can analyzed PD signal"s time-frequency domain simultaneously. On the other hand, using wavelet transform denoising process, included noise signal in detected PD signal is well eliminated. we can propose the true shape of PD signal.
