Abstract
A superconducting device comprises an inductive current limiter with an annular element produced from high-Tc superconducting material. The device is further provided with a soft-magnetic yoke leg enclosed by the material and with a transformer with primary and secondary windings and a soft-magnetic flux element with a plurality of yoke legs. The magnetic flux element is designed to contain between the primary winding and the secondary winding of the transformer the yoke leg of the current limiter, the conductor of one winding producing a switch current for the current limiter.
