In this paper, a GIS partial discharge simulation device is designed. Based on the simulation device, a GIS partial discharge measurement system is developed. The model simulates the 110 kV GIS bus cavity. In this paper, four kinds of discharge physical models including tip defect, suspension defect, air gap defect and particle defect are designed, and the GIS partial discharge measurement system is established. Pulse current detection method and ultra-high frequency detection method are used to test and analyze the data to study the characteristics of different types of partial discharge in GIS.
