A Consideration on Over-current Withstanding Design of Superconducting Power Cables

Abstract

In a design of HTS power cables, the over-current withstanding design is very important. In a conventional case, when one of the 2-circuit power cables failed, the other cable should transport the previous total power continuously. If we adopt this idea also in case of superconducting power cables, the rating current should be decided carefully. In this paper, the authors show a fundamental idea for a short-time withstanding over-current design of HTS power cables.
