Abstract. Detection of decomposition products of sulfur hexafluoride (SF 6) is one of the best ways to diagnose early latent insulation faults in gas-insulated equipment, and the occurrence of sudden accidents can be avoided effectively by finding early latent faults. Recently, functionalized graphene, a kind of gas sensing material, has been reported to show good application prospects in the gas sensor field.

    Jan 30, 2018 · Abstract. To obtain and understand the decomposition characteristics and decomposition process of SF 6 gas under different negative DC voltages, a physical model of the needle‐plate defect is used to conduct decomposition experiments of SF 6 gas. Experimental results show that, under different negative DC voltages, the partial discharge (PD) caused by the needle‐plate defect decomposes SF 6 gas and generates five stable decomposed components, namely CF 4, CO 2, SO 2 F 2, SOF 2, and SO 2.
