Abstract
Waveforms of partial discharge (PD) current and sound waves emitted by a PD are measured in a void between a polyethylene terephthalate (PET) film and an electrode. The measured waveforms are transformed by Gaussian and Mexican hat wavelets. The analyzed patterns are obtained on a plane using both time and frequency information. Then, the relation between the obtained results and the degree of insulation degradation is discussed
