摘要
A serious damage can happen to the power cable manufactured from the high-temperature superconducting (HTS) tapes due to overcurrent conditions or because of technical errors during the cable assembling. To avoid the cable damage in any urgent case, a quick interruption of the transport current is necessary. Comprehensive understanding of the current cutoff time of the HTS tape is required to restart the operation of the power transmission line. In this paper, we applied 100-A transport current to BSCCO and YBCO tapes. After interrupting the current, we measured themagnetic field profiles of each HTS tape. We compare themagnetic field profiles for the fast and slow cuts of the current. The cutoff time is 0.15 ms for the fast cut and 100 s for the slow one. The current density profiles are obtained by solving the inverse problem. Our results show that the magnetic field profiles are quite different from each experimental condition and HTS tape, which are related to the hysteresis of HTS tape characteristics.
