SF6: An excellent dielectric gas in controlled ... to Tammi, there are several important factors behind SF6's dominance. "SF6 is three times more effective than air as an electrical insulator. Switchgear insulated with SF6 takes up less space, is less prone to faults and requires less maintenance than …
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 …
