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 sf6 gas gas, both for insulation and fault interruption. Current transformer. The conventional substations use either live-tank or dead-tank type current transformers with oil/sf6 gas insulation. A porcelain insulator is used to insulate the low potential section of the current transformer from the high voltage zone.

Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in gaz sf6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.Get price
