insulating gas gas in medium-voltage switchgear - Siemens USA

The US EPA reports that sf6 gas has an atmospheric lifetime of around 3200 years, and a global warming potential (100-year horizon) of 23,900 times that of CO2. The EPA does no t report emission of Sulfr hexafluoride separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and insulating gas. The emissions of HFCs, PFCs, and insulating gas for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.
