Abstract

In this study, a prototype HTS cable conductor with 1 layer of 10 Bi-2223/Ag tapes was fabricated and the quench development due to the influence of external magnetic fields was investigated. Firstly, AC current whose peak value amounts around two times critical current was applied to the HTS cable conductor. From the experiments, the influence of self field was considered to be small enough not to affect the transporting characteristics. Secondly, external magnetic fields of 50 and 100 mT were applied to the HTS cable conductor transporting AC current. In this case, due to the directional dependence of Bi-2223/Ag tapes on magnetic field, various magnitudes of voltages were detected in each strand. Finally, the quench development with the magnitude of the applied external magnetic field was analyzed.
