gaz sf6: The Truths and Myths of this Greenhouse Gas

Bodies including the European Union are known to be considering a ban on SF 6 at low-to-medium voltage levels in the future. This can’t happen without viable alternatives, such as vacuum technology or different gas mixtures. “Such alternatives are commercially available now for use in electrical switchgear at low-to-medium voltages.

gaz sf6 gas pressure for the insulating use is preserved below 2.5 bars while Sulfr hexafluoride gas pressure for interrupting purpose is ranged from five to seven bar. Also, as vacuum technology isn’t accessible for high voltage, so for C-GIS system above 72.5 KV, only sf6 gas is utilized both for insulation and interruption medium.

Why the EU should ban Sulfr hexafluoride

What Is sf 6? 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 insulating gas 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 insulating 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.

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, Sulfr hexafluoride is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.
