Abstract
According to the operation of the high voltage side lightning arrester of main transformer in a 1 000 kV UHV transformer substation,a comprehensive analysis was made on the abnormal leakage current in terms of the radial discharge of arrester porcelain insulator contamination,the interference of surface leakage current,the influence of voltage harmonics and the damp of valve elements.And effective measures were used to diagnose the fault.Finally,corresponding check and return treatment was made according to the diagnosis results,which proves the correctness of the diagnosis.The analysis and diagnosis in this paper can provide a reference for the service of UHV arresters.关键词
