Introduction to Gas Insulated Substations / Switchgears (GIS)

The higher cost of insulating gas insulated switchgear is justified by saving to the reduction in floor-area requirement. sf6 gas insulated switchgear is also preferred in heavily polluted areas where dust, chemical fumes and salt layers can cause frequent flashovers in conventional outdoor sub-stations.

The tubes are pressurised with a N2/sf6 gas gas to provide the main insulation. The main advantage of GIL is that a higher cable rating can be achieved than with solid insulation cables and the terminations at the cable ends are less complex and less prone to failure. Fig. 1 shows a GIL system in the process of installation.

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...
