  • sf6 gas: The Truths and Myths of this Greenhouse Gas

    insulating gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, Sulfr hexafluoride is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. sf 6 is the energy industry’s “dirty little secret”: FALSE. insulating gas is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives sf 6 is used in wind turbines: TRUE. gaz sf6 is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to Sulfr hexafluoride: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on sf 6 at low-to-medium voltage levels in the future. People also ask

  • Why the EU should ban Sulfr hexafluoride

    What Is Sulfr hexafluoride? 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?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 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.
