28 rows2010/6/12Dielectric gas. A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges. Dielectric gases are used as electrical insulators in high voltage applications, e.g. transformers, circuit breakers (namely sulfur hexafluoride circuit breakers ), switchgear

Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (SF6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to date. Over a 100 year period, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). SF6 is also a very stable chemical, with an atmospheric lifetime of 3,200 years. As the gas is emitted, it accumulates in the atmosphere in an essentially un degraded state for many centuries. Thus, a relatively small amount of SF6can have a significant impact on global climate change. More information on long lived fluorinated greenhouse gases, their emissions, emission sources, and trends is available on EPA's overview of greenhouse gases page.See more on epa.govTheoretical study of SF6 decomposition on the MoS2 monolayer doped with Ag, Ni, Au, Pt: a first principles study | SpringerLink link.springer/article/10.1007/s10450 019 00025 52019/2/5SF6 as a greenhouse gas, how to efficiently decompose it becomes a hotpot in the environmental field. Based on the first principles calculations, this paper studied the interaction mechanism of SF6 gas molecules on transition metal (TM) doped MoS2 surface. The adsorption energy, energy barrier, charge transfer, density of states and electron density difference have been discussed. The results
