Ac losses in superconducting coils
Electrical Engineering in Japan, 1991 AbstractAC superconducting wire is being developed for such electrical equipment as superconducting transformers and superconducting generators. AC loss reduction is of primary concern in the development of such high‐efficiency equipment. In reducing ac losses, it is necessary to develop assessment methods for ac loss in test samples which have shapes ...

Simulation of Dynamic Resistance and Total Loss of HTS CORC Cables
IEEE Access, 2023 In some high temperature superconducting (HTS) applications, HTS coated conductors carry DC current under external AC magnetic fields. Dynamic resistance occurs when the amplitude of the magnetic field is greater than the threshold magnetic field of the ...
