Green Gas to Replace SF6 in Electrical Grids

Yannick Kieffel; Todd Irwin; Philippe Ponchon; John Owens

Environmental considerations are increasingly taking a front seat in all arenas of our daily lives-political, industrial and societal. Not least among the major concerns are global warming and the greenhouse gases that contribute to it, as their concentration in the air reaches new heights. Hence the power industrys focus on sulfur hexafluoride (SF6) and the need to find a suitable alternative for it in industrial applications. Grid Solutions, a GE and Alstom joint venture, has identified a fluoronitrile based gas mixture dubbed g3-green gas for grid-that is such a alternative.
