  • GIS Owners in California Must Comply With SF6 Regulation

    Jan 11, 2019 · Since 2011, the California Air Resources Board (CARB) has regulated sulfur hexafluoride (SF6) emissions from gas-insulated switchgears (GIS). CARB’s SF6 Regulation applies to all entities that own GIS, including many entities that do not otherwise emit and report greenhouse gas (GHG) emissions such as wind farms, solar parks, and geothermal plants. Accordingly, some companies may not have realized that they are subject to the SF6 requirements.

  • 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...
