    Chemistry. IEEE Transactions on Dielectrics and Electrical Insulation. As one of the most commonly used insulating mediums, in electrical discharge, sulfur hexafluoride (SF<sub6</sub) will decompose in the presence of water vapor and oxygen, producing various gaseous by-products. It is shown that the concentrations and production rates of SF<sub6</sub gaseous decomposition by-products heavily depend on electrical field to gas density ratio (E/N) under corona discharge.

    Jan 30, 2018 · 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.
