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 sf 6 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 gaz sf6 can do in centimeters.Get price

An Introduction to Gas Insulated Electrical Substations

The cost of a GIS would equal the cost of an AIS when the voltage of the substation reached the 345 kV range. As voltages went above the 345kv threshold, GIS facilities would be the cheaper alternative over AIS. Present-day cost analysis have shown though, that the cost of AIS has beenGet price
