  • Emissions of the powerful greenhouse gas SF6 are rising

    The amount of the gas – known as SF6 – in the atmosphere is minute, only about three parts per trillion by volume, but its global warming potential is significant. It’s 23,500 times more warming than carbon dioxide.

  • SF6 Leak Rates from High Voltage Circuit Breakers - U.S. EPA

    sources of SF6 emissions occur from: 1) losses through poor gas handling practices during equipment installation, maintenance and decommissioning; and 2) leakage from SF6-containing equipment.

    The primary design focused on safety, reliability and low maintenance. MEPPI had a reputation for very low SF 6 gas leak emissions, and it increased its stake in the project with a leak rate guarantee of less than 0.1% per unit volume per year for the GIS. An extended warranty that guarantees this leak rate for a long time provided ITC with assurance that leaks should no longer be a problem at St. Antoine.

  • Au Catalyst-Modified MoS2 Monolayer as a Highly Effective

    To ensure the stable operation of gas-insulated equipment, removal of SF6 decomposition products of sulfur hexafluoride (SF6) is one of the best methods. SO2F2 is one of the typical decomposition products of SF6, while the Au-modified MoS2 (Au–MoS2) monolayer is a novel gas adsorbent. Therefore, based on the first-principles calculation, the adsorption properties of the SO2F2 molecule on the
