Electric Power Systems


Kitashiba offers a variety of reactors, including shunt reactors that remain in constant operation to stabilize electricity supply during load variations, and arc-suppression reactors that prevent power failures due to equipment failures and abnormal voltage and protect transmission lines from high-voltage fluctuations.

  • Shunt reactors (ULTrans)

    • Low noise
    • Low power loss
    • High reliability

    Connected in parallel with a power grid, a shunt reactor compensates for phase-leading reactive power to stabilize the grid voltage. Incorporating noise and vibration suppression technology, Kitashiba’s shunt reactors are optimized using a core structure selected according to reactor capacity.

  • Arc-suppression reactors

    Arc-suppression reactors are single-phase reactors. They compensate for the capacitive current that appears on transmission lines in the event of a one-line ground fault. Arc-suppression reactors are used on their own or in combination with a resistor. In the event of a one-line ground fault, the line-to-ground charging current flows to the arc-suppression reactor, causing the arc at the faulty point to self-quench. As a result, arc-suppression reactors protect transmission lines from high-voltage fluctuations and thus prevent power failures.
