SF 6 gas leakage occurred in gas insulated switchgear(GIS) can lead to insulation degradation and serious pollution on atmospheric environment. Based on the specific infrared absorption spectrum of SF 6 gas, infrared imaging method can make the leakage gas clearly visible. As a result, it can rapidly and accurately locate leakage position for on-line equipments. It is concluded from the detection examples that this method is visual and effective for SF 6 gas leakage, and can provide sufficient information for the maintenance strategy of gas leaking equipment.
