Electromagnetic Field Analysis Of High Temperature Superconducting Cable

It is widely acknowledged that the value of critical current in High Temperature Superconducting (HTS) tape has a great influence on B. Therefore, when HTS cable is designed, a method to reduce the B should be considered in order to improve the capacity. This paper deals with the influence of the space between each HTS tape by using 2D analytical method. From the analysis results, it is found that the decrease of the space causes the decrease of B. Moreover, another HTS cable, which has a very small space, is analyzed by 3D analytical method and it is manufactured. The validity of these analysis results are verified by comparison with experimental results.
