Abstract :
The change in PD (partial discharge) pulse shape for a void bounded with LDPE was measured using a time-resolved measurement system with an ultra-wideband detector. Phase-resolved patterns also were obtained by a conventional PD measuring system. The frequency spectrum analysis of PD pulse waveform showed that ageing stages have unique frequency distributions. PD patterns also have different frequency ranges. The frequency distribution was concluded to be applicable to the insulation diagnosis.
