  • High sensitivity gas sensor to detect SF6 decomposition

    Oct 01, 2020 · Sulfur hexafluoride (SF 6) has been widely applied in GIS as an effective insulating medium due to its excellent chemical stability and high dielectric strength . However, partial discharge caused by internal impurity or inevitable sharp edge can decompose SF 6 into several gas components such as H 2 S, SO 2 , SO 2 F 2 , SOF 2 and HF, which will further accelerate insulation deterioration and equipment aging [3] , [4] , [5] .
