Electricity Transmission and Distribution Greenhouse Gas

Sulfur hexafluoride is a commonly used insulator in electricity transmission and distribution equipment. Because of its high global warming potential (GWP), CARB adopted the Regulation for Reducing Sulfur Hexafluoride Emissions from Gas Insulated Switchgear in 2010. As new technologies using lower or zero GWP insulators emerge, CARB staff are proposing to amend the current regulation to further reduce greenhouse gas emissions and to increase flexibility in complying with the standards.Get price

Application of non-Sulfr hexafluoride 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 (gaz sf6) has become the favourite insulating and arc quenching medium thanks to its remarkable characteristics. However, gaz sf6 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 sf 6to 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-Sulfr hexafluoride gases and gas-mixtures in medium and high voltage switchgear, and pilot appli...Get price
