摘要：
Multiresolution of wavelet transform is applied for extracting parting partial discharge (PD) pulses from narrow-band radio frequency noises. Through the numerical simulating experiment, different influential factors in feature extraction of PD pulses are analyzed. by using wavelet transform. On the base of the above research, on-site PD measurements are made to supplement the numerical simulation such that various factors affecting the results are identified. The research results show that wavelet transform can be used to extracting the PD pulses from the strong noises.
