        Abstract: Introduction was made to a kind of faults discharging point location method of gas-insulated metal-enclosed switchgear (GIS) combining subsection forcing with piezoelectric film sensor. Taking the alternating current (AC) voltage withstand test of 110 kV GIS in certain substation for example, this paper gave the checking location process for the discharging points with this location method. The test results show that this location method could realize faults point location rapidly and correctly after the AC voltage withstand of GIS breaking down.
        Key words: gas-insulated metal-enclosed switchgear; alternating current voltage withstand test; discharging point location
