  • SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS

    Advantages of sulphur hexafluoride in gas-insulated switchgears. SF 6 insulation allows safe operation of high- and medium-voltage systems in close areas, since insulation with sulphur hexafluoride requires much smaller safety clearances. Non-dispersive infrared gas sensors (NDIR sensors) from smartGAS are ideal for measuring the SF 6 gas quality and for detecting even very small quantities of the harmful gas.

  • Panel discussion: The pros and cons of using SF6 gas in

    Brighton Mwarehwa: The SF 6 gas is listed in the famous Kyoto protocol as one of the potential greenhouse gases that contribute to the global warming potential of our earth. SF 6 is always used in gas tight compartments, which greatly minimise leaks. As the quantities that leak from the switchgear are low, the contribution to the greenhouse effect can be considered extremely minimal to affect climate changes.

  • Myth About SF6 Gas In Electrical Equipment

    Where is SF6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is SF6 a health hazard? Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of SF6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
