They both have a carbon backbone, with 5 and 4 atoms, respectively.

Mar 20, 2018Sulfur hexafluoride (SF 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases. Recently, this effort has made important progress, with promising alternative gases being identified and tested.Cited by: 70

Apr 11, 2019A significant step was made in this direction at the end of 2018 when the European Commission issued a new tender that aims, among other, to “investigate the existence of alternatives to sulphur hexafluoride (SF6) in switchgear and assess their feasibility and market potential“ and “identify appropriate policy measures for different types of electrical installations using SF6 including

insulating gas has potential significant environmental impacts if it leaks into the atmosphere. Indeed SF 6 is one of the six gases listed in the Kyoto Protocol, with a global warming potential that is 23500 times greater than CO 2. Alternative solutions to SF 6 have been researched for a long time.

Aug 23, 2010SF6 is on the list of greenhouse gases in the Kyoto Protocol (1). SF6 is the most potent of the six main greenhouse gases, with a GWP of 23,000 (5). The United Nations institution that monitors this, the Intergovernmental Panel on Climate Change (IPCC), has since added SF6 gas to the list of extremely harmful greenhouse gases.

The ambition of GEs LifeGRID program is to help reduce greenhouse gas emissions from high-voltage substations via the development of a greener switchgear. The area of focus for LifeGRID is for climate change mitigation through the use of GE’s g 3 as an SF 6-alternative gas in circuit breakers.“Because 420 kV is the highest voltage level used in most European countries, a proven g 3
