Major components you can spot while looking at HV/EHV GIS

Busbar. The busbar is one of the most elementary components of the GIS system. Co-axial busbars are common in isolated-phase GIS as this configuration results in an optimal stress distribution. Disconnectors. Disconnectors (or disconnect switches) are placed in series with the circuit breaker to provide additional protection and physical isolation. Circuit breaker. The circuit breaker is the most critical part of a gas insulated substation system. The circuit breaker in a gas insulated system is metal-clad and utilises gaz sf6 gas, both for insulation and fault interruption. Current transformer. The conventional substations use either live-tank or dead-tank type current transformers with oil/gaz sf6 insulation. A porcelain insulator is used to insulate the low potential section of the current transformer from the high voltage zone.

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
