  • End of life estimation of HV switchgear and GIS substations

    Substation 1: The rated power frequency withstand voltage was not fulfilled. Various flashovers and disruptive discharges appeared even at voltages distinctly below the onsite test voltage of 184 kV. A voltage breakdown could not have been excluded at the next overvoltage event. Substation 2: The rated power frequency withstand voltage was approved. All parts of the GIS substation passed the test voltage of 230 kV.

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, sf6 gas, 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.
