  2. Switchyard reactor - Wikipedia

    en.wikipedia.org/wiki/Switchyard_reactor

    In an electric power transmission grid system, switchyard reactors are large inductors installed at substations to help stabilize the power system. For transmission lines, the space between the overhead line and the ground forms a capacitor parallel to transmission line, which causes an increase in voltage as the distance increases.
