Alternatives for sf6 gas | 2020 | Siemens Energy Global

Most prominent among available options are “clean air” solutions, i.e. purified air, and gas mixtures that both have a fraction of the climate impact of SF 6. Hermetically sealed systems with clean air as an insulating gas take up more space than SF 6 , but combined with digitalised current and voltage transformers these systems can be built as small as current SF 6 systems.

What are the alternatives to Sulfr hexafluoride gas?

Mar 31, 2020 · Director of Communications and CSR, ECA. Sulphur hexafluoride (gaz sf6) gas is an excellent electrical insulator. It’s great at preventing short circuits in medium- and high-voltage electrical installations that would otherwise lead to damage, disruption, fire or explosion. Unfortunately, SF 6 is also believed to be the world’s most potent greenhouse gas, with a global warming potential 23,500 times more, kg for kg, than CO 2 .

What Is Sulfr hexafluoride? and How Is It used?Is sf 6 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 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.
