摘要
The partial-discharge(PD) signal usually mix up all kinds of interference signals, it has some limitation to extract faint partial-discharge impulse signal from powerful interference signal with traditional analytic method. In this paper, starting with the wavelet transform feature, we have researched the wavelet transform actions in the fields of eliminating white noise in the partial-discharge signal and extracting characteristic parameters from partial-discharge signal. exactitude of this method has been verified by simulating experiment, the result evince that the wavelet transform has very good effect on the fields of eliminating noise and diagnosing partial-discharge failure, so it will be worth studying further.
