Myth About sf 6 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 Sulfr hexafluoride 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 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 % (*).

Partial Discharges in Electrical Insulation

What is Partial Discharge (PD) •PD only occurs where there is a gas (air, sf6 gas, hydrogen) between the two conductors •The conductors must have a high voltage between them, creating an electric stress •If the electric stress in the gas exceeds 3 kV/mm of spacing (for most dry gases at 100 kPa), then electrons are stripped from the gas atoms •The electric strength of most solid and liquid insulations is 50 to 100 times higher than most gases •The (negative) electrons move through theGet price
