gis substation analysis Calibration in Singapore

The other factors, such as resonance, disturbance of internal gas, bring abnormal vibration to the GIS shell. Because of the bad effects followed, the components of GIS can be damaged to the leakage which will lead to power failure in serious cases. In this paper, the vibration analysis of a 1000kV UHV substation 500kV area GIS is carried out.

    4.3.2 GIS GIS substations are purposefully compact to reduce overall compound required space. In a single busbar GIS substation, restrictions may be imposed on adjoining bays due to proximity or possibly gas compartment layout. The gas compartment layout will not impact on this substation as both 400kV 110kV substations are double busbar.

    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).
