Impact assessment of F-gas free medium voltage switchgear

Jun 29, 2020 · June 29, 2020. Sulphur hexafluoride (insulating gas) plays an important role as an insulating gas in electrical switchgear at various voltage levels when interrupting and diverting current flows. At the same time, it is one of the most effective greenhouse gases with a very long lifetime and, although the concentration of insulating gas in the atmosphere is currently still very low, it accumulates steadily over the years.Get price

Why the European Union Should Ban gaz sf6 | Energy Central

What Is sf6 gas? and How Is It used?Is Sulfr hexafluoride A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of gaz sf6 Emissions Difficult? Do Better Solutions Exist?ConclusionSulfr hexafluoride 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 sf6 gasproduced (Powell, 2002: 6). Within the electrical industry Sulfr hexafluorideis 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.Get price
