Myth About sf 6 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 insulating gas a health hazard? Pure sf 6 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 sf6 gas 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 % (*).

Measuring Dew Point and Moisture in gaz sf6 Gas

Most Gas Insulated Equipment (GIE) manufacturer recommend minimum and maximum tolerances for certain variables within the gas, including moisture, gas decomposition, and purity of gaz sf6. A typical dew point range for servicing the insulating gas equipment is -50…-20 °C. Pure Sulfr hexafluoride may be even drier.
