Research on Typical Discharge Mode of Power Transformer

Abstract: Five kinds of oil-paper insulation models are designed and produced to simulate typical defects of power transformer. Plenty of discharge spectrogram and discharge impulse waveform are obtained by using digital PD measuring system. PD features of different defects are analyzed, which will be helpful for further research on PD pattern recognition and insulation aging of power transformer.

Key words: Transformer, partial discharge(PD), oil-paper insulation, discharge model
