Why the EU should ban Sulfr hexafluoride

What Is Sulfr hexafluoride? and How Is It used?Is insulating gas 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?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 sf 6produced (Powell, 2002: 6). Within the electrical industry sf6 gasis 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

Sulfr hexafluoride—The Alternative Gas - NETAWORLD JOURNAL

AlternativesReconditioningTrainingConclusionReferencesSome proposed alternatives fall short of Sulfr hexafluoride and would create an enormous economic burden on utilities because it would require a complete overhaul of their gas insulated switchgear (GIS) equipment. We make the case that the industry has an Sulfr hexafluoride handling problem, not an sf6 gasproblem. The industry could make two changes to drastically decrease gaz sf6emissions: 1. Use reconditioned gaz sf6 instead of importing virgin gas. 2. Ensure that trained and certified personnel are using best management and safety practices when handling Sulfr hexafluoride. The United States has a large stockpile of insulating gas gas. From an environmental perspective, reconditioning gas could lower the carbon footprint by removing the need to manufacture new product. Sulfur hexafluoride is 100 percent recyclable, and there is no chemical difference between virgin Sulfr hexafluoride gas and certified reconditioned sf6 gasgas. Any contaminants that occur due to the intrusion of air, moisture, or generation of arc by-products can be removed with the proper process.Get price
