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

  • Substations - an overview | ScienceDirect Topics

    Substation is an important element of power transmission system that has transformers (and other power system components). Transformers at substations, can be classified in different (possibly disjoint) groups, with respect to their voltage levels (power levels), function in a power grid, insulation class, or construction, etc..
