【Abstract】 In this paper, the defect types that lead to partial discharge(PD) in GIS are analyzed. A detecting system of PD for model GIS has been set up. The measurement includes the UHF detection, conventional PD measurement and the spectrum analysis. The PD characteristic of the pairs of metal particles is researched.更多还原
