For decades, SF6 has been a dielectric medium commonly used in electrical power applications, particularly for high voltage equipment. However, SF6 has long been recognized as a potent greenhouse gas and governments have sought to reduce emissions from gas-insulated equipment. The electrical power ind...
among other aspects, and of late, we have started introducing new products and offers with value propositions for the Indian market as well. We are attempting to shift our dependence on SF6, a greenhouse gas that largely contributes to global warming. We...
This paper evaluates the insulation performance of gas mixtures of trifluoroiodomethane and carbon dioxide (CF3I-CO2) in a medium voltage switch disconnector. Practical testing compares the results of CF3I-CO2 against SF6 to examine whether CF3I-CO2 could be a viable alternative when directly subst...

ALTERNATIVE GAS INSULATION IN MEDIUM-VOLTAGE SWITCHGEAR SF6 is used as insulation gas in gas-insulated switchgear (GIS) today since the technical performance of SF6 perfectly matches to the technical requirements. The drawback of SF6 is the high global warming potential (GWP) of about 23.500 ......
Japanese power industries are now makingrnvarious efforts to reduce SF6 emission in gas insulatedrnpower equipment. One such effort is the possiblernapplication of SF6/N2 mixed gas as substitutes to purernSF6 in the gas insulation. This paper describes thernJapanese plans for the reducti...
The aim of this study is to reduce the amount of harmful substances in the effluent gas in the plasma cleaning process of vacuum chambers by substituting the greenhouse gas SF6. We present comparative studies for the optimised cleaning rates which are based on C4F8/O2 and NF3 diluted with He...
