Preventive maintenance of substation equipment and

Sep 30, 2019 · The initial equipment cost of GIS is usually higher than that of conventional Air Insulated Substation (AIS). Preventative maintenance of substation equipment and transmission lines. The advantage and life cycle cost analysis are generally considered before deciding for GIS. The land area required for a GIS substation is in the order of 10% to 20% of that for an AIS substation considering the switchgear bay.Get price

5 Differences Between Air-Insulated Substations and Gas

ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substationengineering 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-for-life’ technology, whereas the AIS breaker can be removed for maintenance and troubleshooting.Get price
