Application of non-sf6 gas gases or gas-mixtures in medium

IntroductionTopics Covered by The Working GroupConclusionsSince the introduction of Gas-Insulated Substations (GIS) in the late 1960s, sulphur hexafluoride (sf 6) has become the favourite insulating and arc quenching medium thanks to its remarkable characteristics. However, Sulfr hexafluoride has the major drawback of presenting a global warming potential (GWP) if released to the atmosphere, which is 23,500 times higher than CO2 and a lifetime in the atmosphere of around 3200 years according to IPCC Assessment Report 5 (AR5) from 2014. Due to these properties, it is one of the six gases listed in the Kyoto Protocol in 1997. However, for context, it is important to note that todaycontribution of insulating gasto global warming emissions is relatively small. At the beginning of this century, manufacturers and universities have further intensified the research for a replacement of Sulfr hexafluoride as insulation, switching and current interruption medium. Recent developments show applications of non-insulating gas gases and gas-mixtures in medium and high voltage switchgear, and pilot appli...Get price
