sf6 emissions DETERMINATION for Transformers

Sep 03, 2018sensotec / September 3, 2018. Sulphur hexafluoride (sf6-gas) is a man-made gas comprising of one sulphur and six fluoride atoms. sf6 gas gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers

  • SF6 gas in medium-voltage switchgear | TD Guardian

    The US EPA reports that SF6 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 SF6 separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and SF6. The emissions of HFCs, PFCs, and SF6 for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.
