Abstract

Waveforms of partial discharge (PD) current and sound wave emission by PD are measured in a void between a polyethylene terephthalate (PET) film and an electrode. The measured waveforms of PD current and sound wave are transformed by Gaussian and Mexican hat wavelets. The relation between the obtained results and degree of insulation degradation is discussed. As a result, it was clear that wavelet analysis results could be used in degradation diagnosis of an insulator
