Abstract This paper introduce an 110kV GIS internal heat with partial discharge defects due to isolation switch was not in the right place, using ultrasonic detection method, the ultra-high frequency detection method and the analysis method to components of SF6 gas to detect the partial discharge. Analysis of the causes of defects, the processing has a certain reference to similar defect.
