Partial discharge testing is an essential, proven tool that can locate and identify flaws in the insulation of cables, bushings, windings, tap changers and a myriad of other assets and accessories. In the early stage of ageing of insulated materials, detection of deteriorating performance may be difficult to detect by traditional test methods.

IntroductionTopics 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 K…See more on electra.cigre.orgPeople also search forapplication of sf6 gasesapplication of gases in gas insulated switchg…application of sf6 gasapplication of gases in sf6application of sf6Things You Should Know About MV GIS EEP electrical engineering portal/things you should know about medium voltage gisEnvironmental ConcernsSafety ConcernsSpecial Handling ProceduresInstallation ConcernsOperation and Maintenance ConcernsEnd of Life and Recycling ConcernsThe insulating gas used in MV GIS switchgear,sulfur hexafluoride (SF6), is a highly potent greenhouse gas with a global warming potential 23,900 times greater than CO2. SF6 also has an atmospheric life of 3,200 years, so it will contribute to global warming for a very long time.
