Extraction and Counting of Partial Discharges under Pulse Voltage

  • The extraction and counting method for partial discharge(PD) under pulse voltage was proposed.dB6 and dB2 wavelet packages were used to filter high and low frequency interferences respectively based on an analysis on correlation coefficient between simulation signals and extracted signals.A phase window was used to remove oscillating signals of PDs generated by sensors according to the characteristics of PDs under pulse voltage.PD phases were defined based on sampling rate,sampling length and zero-crossing of pulse voltage to analyze phase resolved patters(e.g.,-n and -q-n plots) under pulse voltage.Experiment results indicate that the proposed methods are effective for extraction and counting of PDs.
