HV Capacitor DC Partial Discharge Character Parameter Analysis

摘要

Under Direct Current voltage, Partial Discharge Analysis has great significant, the analysis for PD datum is very important. Toward discrete and limited datum in PD test for HV capacitor, the paper refers to statistical theory, and selsects the trimmean for preceding disposing. Then finding the character parameters (kurtosis, Skewness, Correlation coefficient, Variance coefficient etc.), which explore that different status capacitors have different PD character parameters, and help to distinguish the respective insulating capability from the same types capacitors. All these are great meaning for future study.
