Acoustic signals of partial discharge are very important for detecting insulation characters in power capacitors.In this paper an acoustic detecting instrument is used to collect the acoustic signals of partial discharge in power capacitors
and characteristics of these signals are analyzed.Therefore
characteristics of three kinds of typical signals and reasons of their formation are introduced.At the same time
rejection of narrow-band wave and denoising using wavelet are introduced to reject noises.The outcome is satisfying.
