Abstract
The combined diagnostic method for partial discharge( PD) detection of gas insulated switchgear( GIS) is presented in this paper. The inner fault of GIS was found by the combined diagnostic method
the discharge power was located by the time difference method
and the potential defect is eliminated in the end to prevent serious accidents. The live application shows that the method presented in the paper can diagnose the defects in GIS more successfully.
