<p>. A current-limiting device for A,C, systems comprises saturable reactors with superconducting bias windings which maintain the reactors in saturation for normal A.C. loads. Excess current drives one of the reactors out of saturation on alternate half-cycles and thus creates a large flux change with accompanying back EMF to limit the current. The device is applicable to the connection of electric power distribution systems to limit fault currents and to allow power transfer without loss of stability.</p> |
