Essentials of SF6 monitoring | T&D Guardian Articles | USA SF6 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.
SF6 handling in industry | Sauer Compressors greenhouse potential of SF6 is estimated to be 23,000 times higher than that of carbon dioxide. SF6 can remain stable in the atmosphere for up to 3,200 years. As a result, it can only be used in closed circuits in industry. For maintenance purposes, SF6 must be evacuated from gas insulated switchgear.
Sulfur hexafluoride - Wikipedia hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an excellent electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.
