【Abstract】 Based on the characteristics of configuration of gas-insulated substations (GIS) and partial discharge in GIS, a disc coupler and a loop coupler for continuous monitoring partial discharge in GIS is designed and the response characteristics of two couplers are investigated. The results of PD signal measured by the couplers in GIS are given, and it is shown that the designed couplers can be used in the measurement of partial discharge in GIS.更多还原
