Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, Sulfr hexafluoride, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in insulating gas gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.Get price

End of life estimation of HV switchgear and GIS substations

Jun 10, 2016 · When assessing the service life of GIS, further criteria besides the insulation performance have to be taken into account, including wear and mechanical performance of the switching equipment, which can also limit the lifetime of GIS. In conventional substations a probabilistic data analysis of high and extra high voltage equipment can be used to optimise and prioritise maintenance work.Get price
