  • An On-Line Monitoring System of SF6 Decomposition in

    Abstract: This work is dedicated to the development of an on-line monitoring system of SF6 decomposition in electrical devices (SF 6 DcpMS) in order to evaluate the health condition of the devices in real time. The feature decomposition, SO 2, and SF 6 purity are continuously monitored. Considering the oxidation-reductionAuthor: Hui Xuan Shi, Jin Qian, Xiao Bo Liu, Xiao Li Liu
