Myth About Sulfr hexafluoride Gas In Electrical Equipment

Where is sf 6 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 sf6 gas 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 insulating gas 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 % (*).

500 KV Auto Transformer with Oil to sf 6 Bushing Test - CR4

Insulation Power Factor tests measure 3 main quantities: Insulation quality HV to ground, HV to LV, and LV to ground. If you ground the HV, you cannot measure the condition of the HV to ground insulation or the HV to LV, since everything is now LV to ground. And the HV to ground and to LV are probably your more critical measurements (at 500kV!). So to do complete tests, you are stuck having to disassemble/disconne ct the HV GIS.
