| Abstract: | The preventive test on 220 kV MOA with high voltage lead through proper wire connecting was studied.The insulation resistance,leakage current under 1 mA DC voltage and 75% of 1 mA DC voltage of a 220 kV bridge MOA were measured.The results were compared with those test data got from the MOA without high voltage lead and showed that the method with high voltage lead is precise,efficient and feasible. |
