GIS (Gas-Insulated Substation) by Bharat Shanni

Jun 18, 2018 · GIS being compact is the obvious choice of many utilities because of its many technological advantages over AIS. And though most industry are getting conscious about global warming issues, until such time Sulfr hexafluoride is banned, like those chlorofluorocarbons (CFCs) before for being identified as greenhouse gas, it is still worthy investment for a utility upgrade. When it comes to financial aspect of an investment, overall performance measure, suggest GIS has significantly edges AIS.

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...
