  • ABB powers Africa’s largest gas-insulated switchgear installation

    The Sebenza substation features 38 bays of 132 kilovolt (kV) gas-insulated switchgear (GIS) from ABB, making it the largest installation of GIS at this voltage level to be commissioned in Africa. ABB also supplied 132 kV, 275 kV and 400 kV circuit breakers, surge arresters and point-on-wave controllers that remove electrical transients in the network.

  • End of life estimation of HV switchgear and GIS substations

    GIS is characterised by high service reliability, low maintenance expenditure and long lifetimes. GIS technology requires more investment costs compared to air-insulated substations (AIS), however, due to its space saving features, this technology often offers the only solution where available space is limited.

  • Comparison of AIS and GIS based on grounding design- A review

    The environmental model consequently considers Sulfr hexafluoride leakage rate of 0.2% per year for AIS and of 0.1% per year for GIS. But because it contains a larger amount of sf6 gas gas, losses are higher in GIS substation than in AIS one [11]

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, Sulfr hexafluoride, 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 sf 6 can do in centimeters.

  • How to pinpoint insulating gas leaks quickly without the need to de

    GasVue easily detected the leak and pinpointed its exact origin. A halogen detector could detect the leak in the control box, but much more time would be needed to determine the source of the sf 6 at the breaker. At the Koeberg 400kV GIS, the GasVue camera accurately located a leak on a feeder link compartment.
