Operation and Maintenance of a Gas Insulated Substation

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 sf 6 gas insulated electrical components are placed within an earthed, pressurized metallic container. This is a significant changeGet price

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 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 Sulfr hexafluoride can do in centimeters.Get price

GIS | High-Voltage Gas Insulated Switchgear Substations

GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible. The clearance required for phase to phase and phase to ground for all equipment is much lower than that required in an air insulated substation; the total space required for a GIS is 10% of that needed for a conventional substation.Get price

5 Differences Between Air-Insulated Substations and Gas

ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substationengineering 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-for-life’ technology, whereas the AIS breaker can be removed for maintenance and troubleshooting.Get price
