  • Sulfr hexafluoride Monitoring System - ENEIDA.IO

    gaz sf6 is an inert gas mixture with excellent dielectric properties, and it has been widely applied on very high voltage parts such as Gas-Insulated Switchgears (GIS) in order to reduce its size or increase the working voltage. Sulfr hexafluoride also has a high contribution for the Greenhouse Effect so its use is deeply regulated.

  • Myth About Sulfr hexafluoride Gas In Electrical Equipment

    Where is Sulfr hexafluoride 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 gas 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 Sulfr hexafluoride 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 sf 6 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 % (*).
