• sf6 gas replacements: switching how we think about power transmission

    In addition, “direct” 3-phase testing where power is provided from a single source eliminates any concerns over the equivalence between test and real service conditions. This kind of testing requires facilities such as the KEMA High-Power Laboratory in Arnhem, the Netherlands and KEMA Laboratories – USA in Chalfont, Pennsylvania that can

  • Replacing sf 6 is Switching How We Think of Transmission

    One potential issue around certifying such components is that many of the relevant international standards for testing GIS focus onSF 6 and may not be directly transferable to green alternatives. IEC 60376 and 60480, for example, provide guidelines for purity and other technical specifications for ‘new’ and ‘re-used’SF 6 respectively

  • Myth About gaz sf6 Gas In Electrical Equipment

    Where is insulating gas 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 sf 6 a health hazard? Pure Sulfr hexafluoride 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 sf 6 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 Sulfr hexafluoride 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 % (*).
