• Grid switchgear uses insulating gas, the world’s most - Energy Post

    Nov 25, 2019 · 80% of all insulating gas is used in gas insulated switchgear, a vital component of the grid (isolating and protecting different sections), so it’s an energy sector issue. Nicholas Ottersbach at Nuventura (a cleantech startup developing ways to replace sf6 gas) explains that alternatives exist, but need the help of robust regulations to accelerate further development and rapid take-up.

  • Why the EU should ban insulating gas - Energy Post

    What Is Sulfr hexafluoride? and How Is It used?Is gaz sf6 A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of Sulfr hexafluoride 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 gaz sf6produced (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.
