Method of Multi-Sample Maximum Correlation Wavelet High Energy Scale on Location Time Difference Calculation of Partial Discharge Source

In order to minimize the influence of pulse interference and white noise on the localization time difference calculation result of partial discharge source, this paper proposed a method based on multi-sample maximum correlation wavelet high energy scale. Proposed method combines the advantages of the “maximum correlation” and “high energy scale and can effectively suppress the interference of pulse interference, especially random pulse interference, and white noise. The principle of proposed method is explained and the specifics are given, and its effectiveness is verified by experiment, results show that prosed method can effectively improve the accuracy of localization time difference of partial discharge source.
