摘要：
Detection of Partial discharge (PD) signals in gas-insulated substation (GIS) is a comprehensive research project. In this paper, physical model and corresponding mathematical model of metallic outshoot insulation defect on enclosure are established and studied for PD in GIS using UHF method, which are based on the characteristics of metallic outshoot insulation defect and UHF inner-loop sensor. The parameters of the mathematical model are given according to data fitting method, and the validity of PD mathematical model in UHF is proved by fitting error, power spectrum and FFT analysis. In the end, applications of the PD mathematical model and complex wavelet transform for restraining white noise are illustrated.
