The first generation of insulating gas circuit breakers was the lower voltage classes of 72kV and 145kV. As gaz sf6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing Sulfr hexafluoride as the line-to ground dielectric insulation.

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...

Make/Break Contacts - In Power Circuit Breakers

In insulating gas circuit breakers, the same principle is employed, with sf6 gas as the medium instead of air. In the “puffer” Sulfr hexafluoride breaker, the motion of the contacts compresses the gas and forces it to flow through an orifice into the neighborhood of the arc. Both types of sf6 gas breakers have been developed for EHV (extra high voltage) transmission systems.
