According to the problem that the intelligence is not high of the recognition of GIS PD types by SF 6 decomposition components, using the real 110kV GIS platform, simulating two kinds of insulation defects PD of SF 6 gas, and making the research on the change of the four kinds of gases of CO 2 ,CF 4 ,SO 2 F 2 ,and SOF 2 ,then making the research on the ratio of components of c(SOF 2 )/c(SO 2 F 2 ), and c(CF 4 +CO 2 )/c(SOF 2 +SO 2 F 2 ). The results show that the two types of ratio of
more » ... of the GIS bus spike PD and the insulator surface PD are significantly different. Therefore, the two types of ratio of components can as the features to identify the GIS bus spike PD and the insulator surface PD.
