  • SF6 Gas Measurement Theory - MBW Calibration AG

    Daniel Mutter, MBW Calibration, Wettingen, Switzerland Sulphur hexafluoride, SF 6 , is a non-toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability. Due to its high dielectric strength, it is particularly suited for application in high power circuit breakers as well as in high-voltage cables, transformers, and switchgears.

  • 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 % (*).

    SF6 gas pressure for the insulating use is preserved below 2.5 bars while SF6 gas pressure for interrupting purpose is ranged from five to seven bar. Also, as vacuum technology isn’t accessible for high voltage, so for C-GIS system above 72.5 KV, only SF6 is utilized both for insulation and interruption medium. Gas Insulated Switchgear Types
