  • insulating gas: No Leak Too Small | TD World

    The Trafag gas monitors do not have any control function on the breakers to isolate sections of the GIS; instead, they only supply both a low and low-low alarm indication. The theoretical design limit of the GIS bus and breakers is that at zero SF 6 pressure, the components' insulation systems will withstand 1.0 per unit line-to-ground voltage. Throughout the design process, this fail-safe philosophy was employed when practical.

  • 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...
