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

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 insulating 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 gaz sf6 can do in centimeters.Get price

Gas Insulated Switchgear : Working, Testing Its Applications

ComponentsAdvantagesDisadvantagesGas Insulated Switchgear ApplicationsThe Gas-insulated switchgear design can be done using different components like circuit breakers, bus bars, disconnectors or isolators, transformerslike voltage and current, earth switches, lightning arresters, and surge arrestors. When the substation is connected with gas-insulated switchgear then it is called GIMES or gas-insulated metal-enclosed substation. This kind of technology is not invented recently but it is available for the past 30 years. In gas-insulated medium-voltage switchgear, Sulfr hexafluoride gas works like an insulation material whereas the vacuum technology is mainly used for the purpose of interrupting. Even though, for both insulation and interruption, the Sulfr hexafluoride gas can be used in several medium voltage gas insulated switchgear systems. However, for such devices, Sulfr hexafluoride gas pressures are dissimilar for insulation as well as an interruption. For insulating, this gas pressure is usually kept under 2.5 bar, whereas for interrupting, it is ranged from 5 – 7 bar.Get price
