Gas insulated VS Air insulated substations

Working PrincipleAdvantages of GISDisadvantagesApplicationsA point of note is that the GIS contain the same compartments and components as the normal (AIS) setups. The only difference is the insulation medium, and of course the size. The live components and parts are insulated in metal enclosures filled with Sulfr hexafluoride gas at moderate pressure. Each compartment housing the live part is gas tight, with respect to each other. This ensures that the gas does not pass to the neighbouring modules, as well as ensure that gas monitoring is simpler and independent. ‘O’ rings are installed at the equipment and enclosure flanges to provide the gas tightness. Another important installation is a gas monitoring system. This includes an integrated alarm system, automatic tripping, and lockout in case of low pressure due to leakage.

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...
