66KV Sulfur Hexafluoride Micro water standard
Sulfur hexafluoride (SF6) is primarily of anthropogenic origin but also occurs naturally. The troposphere concentration of SF6 has increased from a steady state value of 0.054±0.009 to more than 4 parts per trillion volume during the past 40 years. An analytical procedure was developed for measuring concentrations of SF6 to less than 0.01 fmol/L in water.

medium voltage insulating gas High-voltage switchgear standard
medium voltage insulating gas High-voltage switchgear standardIntroductionTopics Covered by The Working GroupConclusionsSince the introduction of Gas Insulated Substations (GIS) in the late 1960s, sulphur hexafluoride (SF6) has become the favourite insulating and arc quenching medium thanks to its remarkable characteristics. However, 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 today's contribution of SF6to global warming emissions is relatively small. At the beginning of this century, manufacturers and universities have further intensified the research for a replacement of SF6 as insulation, switching and current interruption medium. Recent developments show applications of non SF6 gases and gas mixtures in medium and high voltage switchgear, and pilot appli...See more on electra.cigre.orgALTERNATIVE GAS INSULATION IN MEDIUM VOLTAGE SWITCHGEAR library.e.abb/public/7c9414ae3092461fbabe27335cbc47d3...Since SF6 was introduced into gas insulated medium voltage switchgear (GIS) in 1982 the market for thistechnology has grown continuously. SF6 insulation offersthe highest reliability and provides the most compactdesign. The high voltage part is decoupled from theenvironment so that maintenance is significantly reducedand related outages or failures can be prevented. Spacesaving is a premium in larger cities. A reduced footprintallows installations in very compact switchgear rooms aswell as the replacement of older equipment with thepossibility to extend the switchgear.
