SF6-alternative gases for application in gas-insulated ...· The environmental problems caused by greenhouse gases have received unprecedented attention. Sulfur hexafluoride (SF 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases.
Fundamentals of medium voltage switchgear | Eaton insulated switchgear (GIS) has sealed enclosure(s) filled with insulating gas sulfur hexafluoride (SF6) or mixture of SF6 and other insulating gases recently released to the market. The gas-filled sealed enclosure facilitates a compact, low-profile installation.
Characterization of GIS Spacers Exposed to SF6 ...: SF6 gas-insulated switchgear is a sealed system, but low- level contamination can accumulate and affect spacer performance. The degradation of a number of spacer materials exposed to either direct arcing conditions or arc by-products was investigated to correlate their surface molecular features with changes in electrical performance.Cited by: 51
