A.c. loss measurements were made at a power frequency of 50Hz for superconducting Nb-Zr-Ti alloy wires, and for the single and multi-core composites.
The a.c. losses of the alloy wires were found to be equal to those calculated due to the Bean-London model. The total a.c. losses of the single-core composites were calculated due to the Bean-London model for the superconducting single wire and then due to eddy-current losses for the copper matrix. The calculated value agreed well with the measured value for the single-core composites.
The losses of the multi-core composite were nearly equal to those calculated of due to the proposed model, in which this composite was approximated to an equivalent cross-section single composite.
