N2 - In high temperature superconducting (HTS) AC applications, HTS tapes are assembled into a conductor with a high current capacity and transport AC current in an AC magnetic field generated by currents in neighboring tapes. It is important to clarify the AC loss characteristics of each HTS tape in the assembled conductor. In this work, we compared measured and numerical analysis of AC transport current loss characteristics in three HTS tapes with edge-to-edge or face-to-face configuration and parallel or anti-parallel transport currents. Losses were measured by the calorimetric method, which gives actual losses regardless of the electro-magnetic environment around the sampled tape. The numerical analysis is based on the relationship between the current distribution and the inductive voltage. Our results show that the AC transport current loss in HTS tapes in an assembled conductor depends on the tape arrangement and the direction of the transport current.
