    6 is introduced via a permanent valve (like STS type – Siemens uses a clenched tube). The equipment are "Helium Tight" tested, and, in case of leak, the leakage point is detected with SF 6. Then the apparatus is filled with SF 6. The counter, placed next to the gas valve gives the mass (weight at sea level) of SF 6 included in the switchgear. Then this mass is hand written on the CAPIEL label affixed to the circuit

  • Electricity Transmission and Distribution Greenhouse Gas

    Sulfur hexafluoride is a commonly used insulator in electricity transmission and distribution equipment. Because of its high global warming potential (GWP), CARB adopted the Regulation for Reducing Sulfur Hexafluoride Emissions from Gas Insulated Switchgear in 2010. As new technologies using lower or zero GWP insulators emerge, CARB staff are proposing to amend the current regulation to further reduce greenhouse gas emissions and to increase flexibility in complying with the standards.
