Abstract

We investigated the validity of AC transport current loss measurement in a high temperature superconducting (HTS) assembled conductor using the four-terminal method. We tested the effect of different arrangements, transport current direction, and transport current distribution in the assembled conductor. Neither the arrangement nor direction of the transport current affects the accuracy of the AC transport current measurement. When transport current distribution in an assembled conductor is unbalanced, it is possible to deduce the loss by the addition of the multiple of the current and voltage from the potential lead loops in each tape. If the transport currents in each HTS tape of the assembled conductor are not uniform and only transport current of the assembled conductor is measured, the AC transport current loss is not estimated exactly.
