Myth About gaz sf6 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 gaz sf6 a health hazard? Pure insulating 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 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 % (*).

What Is sf6 gas? and How Is It used?Is sf 6 A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of insulating gas Emissions Difficult? Do Better Solutions Exist?Conclusioninsulating gas is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry sf 6is used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.
