N2 - Partial discharge (PD) detection and recognition are of great slgnificance to the condition monitoring of gas-insulated switchgear (GIS). The study focuses on the development process of PD creeping discharge induced by metallic particles in GIS. A GIS simulation experiment platform which was set up according to the actual operating conditions of GIS was employed for this. The discharge pattern of various stages was measured by pulse current method, meanwhile the characteristic parameters which can characterize the severity of PD effectively were extracted. Intensified CCD (ICCD) was also used to record the evolution process of PD. At last, the PD creeping discharge development was divided into 3 stages, which was manifested by K-means clustering algorithm, and they are corona discharge domination, coexistence of corona discharge and surface streamer discharge and surface streamer discharge domination respectively.
