Research on the Eddy Current Losses in the Stabilizer and Outer-Cryostats of the High-Tc Superconducting Power Cable System

The structure of a high-Tc superconducting power cable system is composed of these parts; (from the outer section) a liquid nitrogen cryostat, a vacuum cryostat, multi-layer high-Tc superconducting cable cores and a stabilizer which is used as the current bypass during the quench period. In this paper, the eddy current losses in the stabilizer and both cryostats during the stable driving period of the high-Tc superconducting power cable system are calculated by the numerical method. And the optimal conditions of the stabilizer and both cryostats, that minimize the eddy current losses, are derived from the analyzed results. The optimal results can be applied to the design and manufacture of the high-Tc superconducting power cable system
