In this study, we investigated AC transport current measurement using a pick-up loop. In a single HTS tape the correction factors for different pick-up loop shapes correspond with the experimental and numerical results. In an assembled conductor, we experimentally investigated the difference in the correction factors for the serial and parallel connected transport current in each HTS tape. In parallel mode, the correction factor has a constant value against the total transport current, while in serial mode the correction factor varies. These results can be explained by the relation between the transport current distribution in each HTS tape and the position of the pick-up loops.
