  • Gas-insulated Switchgear (GIS) Testing - OMICRON

    Gas-insulated Switchgear (GIS) Testing. Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (sf6 gas) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS.

  • 5 Differences Between Air-Insulated Substations and Gas

    ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substation engineering uses the gas sulfur hexafluoride for insulation, whereas AIS uses air insulation in a metal-clad system. Sulfur hexafluoride is five times heavier than air and offers excellent extinction behavior. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test). GIS systems use fixed, mounted circuit breakers. The sealed mounted breakers are a ‘sealed...

    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 gaz sf6 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.
