Economics Between Conventional and Gas Insulated Substation

The new GIS substation, with its associated disconnect switches, ground switches, control house and other equipment, was constructed in a (46-m by 20-m) area. It replaces a non-sectionalized air-insulated 69-KV switch rack at GWP’s Grayson Power Plant, which occupied a (21-m by 62-m) space for nearly 34 years.Get price

Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, sf6 gas, 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 sf6 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 sf 6 can do in centimeters.Get price
