  • Byproducts of Sulfur Hexafluoride (SF6) Use in the

    Detection Procedures and Guidelines SF 6 byproducts are difficult to detect chemically under normal working conditions. The presence of various SF 6 electrical discharge decomposition products and impurities (as well as the presence of SF 6 itself) makes measurement of the different byproducts problematic. A recent report in Transmission and

  • The SF6 Decomposition Mechanism: Background and

    Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly reduce theCited by: 1
