Because Sulfr hexafluoride has a global warming potential that is almost 24,000 times greater than CO2, it gets a lot of attention. And since the electric power industry is responsible for nearly 80% of the world’s usage, our industry has taken significant steps to reduce or eliminate the emissions from gas insulated switchgear.

The process is reversible, so that nearly all of the Sulfr hexafluoride recombines after interruption. Thus, very little of the Sulfr hexafluoride is "used up" during interruption, particularly for interruption of moderate (load) currents. insulating gas dissociates during arcing into its atomic constituents, one sulfur atom and six fluorine atoms.
