An On-Line Monitoring System of insulating gas Decomposition in

Abstract: This work is dedicated to the development of an on-line monitoring system of gaz 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-reduction reactions of SO 2 electrochemical sensor during detection, the methodology of utilizing the air in the electrical device is proposed based on the tests of serving devices.Get price
