CEB: GIS SUBSTATION

CEB has built an indoor power substation in Rodrigues. To increase reliability and embrace modern practices, the CEB is planning to construct a Gas-Insulated Substation (GIS) type substations. Previous CEB substations are Air-Insulated Substation (AIS) types which use atmospheric air insulation. A GIS uses a superior dielectric gas, gaz sf6, at moderate pressure for insulation.Get price

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 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 insulating gas can do in centimeters.Get price
