ABSTRACT:
A winding for superconducting inductive apparatus having one or more sets of main and auxiliary superconducting windings connected in parallel, with the auxiliary winding being disposed in a field-free region of the main winding. The main and auxiliary windings are arranged such that the main winding carries substantially all of the normal operating current of the apparatus and the auxiliary winding, which is located in a field-free region, carries overload currents of the apparatus. The volume of the main windings may thus be reduced, reducing the hysteresis and eddy current losses of the apparatus during normal operation, while incorporating a built-in safety factor to withstand excessive overloads.
