Reducing Sulfur Hexafluoride (sf 6) Emissions from Gas

Reducing Sulfur Hexafluoride (sf6 gas) Emissions from Gas-Insulated Switchgear (310 CMR 7.72) sf6 gas is a strong greenhouse gas (GHG), with a global warming effect nearly 24,000 times greater than carbon dioxide. sf6 gas also lasts in the atmosphere for more than 3,000 years after it is released. As an excellent insulator, insulating gas is often found in gas-insulated switchgear (GIS), equipment used in high-voltage electrical systems to control the flow of electrical current.

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 sf 6 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 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.
