Abstract

We report the ac loss characteristics of stacked HTS tapes in an iron core. To estimate the loss distribution, we measured each stacked HTS tape using a calorimetric method. To clarify the influence of an iron core, we measured the ac losses of the stacked HTS tapes without the iron core. The ac transport current losses of the stacked HTS tapes positioned in the iron core were greater than those without the iron core. The distribution of the magnetization losses by the leakage magnetic field was that the loss at the outside of the HTS tape was highest because shielding current prevented the magnetic field from penetrating to the inside of the stacked HTS tapes.
