Reducing Sulfur Hexafluoride (gaz sf6) Emissions from Gas

Reducing Sulfur Hexafluoride (insulating gas) Emissions from Gas-Insulated Switchgear (310 CMR 7.72) Sulfr hexafluoride is a strong greenhouse gas (GHG), with a global warming effect nearly 24,000 times greater than carbon dioxide. sf6 gas also lasts in the atmosphere for more than 3,000 years after it is released.

Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing".
