This study investigated the current distribution in three-strand transposed parallel conductors made of REBa2Cu3Oy (RE = rare earth) superconducting tapes under applied AC magnetic fields. The validity of the theoretical expression for the additional AC loss caused by the formation of three-strand transposed parallel conductors was verified through experiments. The current distribution and branch ratio in the three-strand conductor were measured and compared with the calculated values derived from the theoretical expression, showing good agreement.
We investigated current distribution in three-strand transposed parallel conductors consisting of REBa2Cu3Oy (REBCO, RE = rare earth) superconducting tapes under applied AC magnetic fields. We recently derived the theoretical expression for the additional AC loss caused by the formation of three-strand transposed parallel conductors and proved its validity through experiments. However, the conditions of each strand and current distribution have not yet been discussed. Accordingly, we measured the current distribution and compared it with the calculated distribution derived using the theoretical expression. From the results, we found that the current branch ratio of the three-strand can also be predicted via the theoretical expression.
