Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, gaz sf6, 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 Sulfr hexafluoride 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

Operation and Maintenance of a Gas Insulated Substation

A major difference between conventional air insulated substations (AIS) and the gas insulated substations (GIS) is that the gaz sf6 gas insulated electrical components are placed within an earthed, pressurized metallic container. This is a significant change in operating the switchgear with circuit breakers, disconnectors, and switches earthGet price
