SF6-alternative gases test

SF6-alternative gases test

A tracer gas leak test can be used to test parts with very low leak rates that are outside the range for conventional air-flow pressure decay and mass flow testing, or to replace bubble test methods. The tracer gas leak test uses escaping tracer gas to identify micro-leaks in the range of 1x10 -4 to 10

  • Alternative Environmentally Friendly Insulating Gases for

    Sulfur hexafluoride (SF6) shows excellent insulation performance as an insulating gas. It is suitable for various climate conditions due to its low boiling point (−64 &C). Therefore, it has been widely used in power grid equipment. However, its global warming potential (GWP) is 23,500 times higher than that of CO2. Thus, it is imperative to find an environmentally friendly insulating gas

  • Alstom unveils worlds first high-voltage equipment

    At the 2015 Hanover Fair, Alstom is presenting two first high-voltage applications using g 3 (green gas for grid), a gas mixture that can replace SF 6 for high voltage air-insulated (AIS) or gas-insulated switchgear (GIS) applications. SF 6 is a potent greenhouse gas commonly used as an electrical insulator. In August 2014, Alstom became the first company in the world to offer the electrical
