An alternative to Sulfr hexafluoride in electrical switchgear - EE Publishers

However, sf 6 is a greenhouse gas and the life-cycle management costs incurred when handling insulating gas, particularly when the decommissioning of ageing substations is on the increase. These costs will rise further as the demand for electricity, and, therefore, gas-filled high and medium-voltage switchgear, increases.Get price

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 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 gaz 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 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 % (*).

Health and environmental dangers of insulating gas-filled switchgear

SF 6 gas in switchgear. SF 6 was discovered around the turn of the twentieth century and, by the 1950s, the electric power industry in the USA widely praised SF 6 as a highly favourable gaseous dielectric medium in high and medium-voltage circuit breakers, switchgear, gas-insulated substations, and other electrical equipment.Get price
