Abstract

Although the shape of high-temperature superconducting (HTS) tape is not good for cables, many researches are being progressed like Roebel conductors, compact cables, and HTS cable in conduit conductors. These cables can show good performances for dc application. However, the ac loss problem due to the shape of HTS tape has not been solved yet. In this paper, the ac loss characteristics of the striated HTS compact cable were analyzed. We made striations on the HTS tapes that composed the compact cable. The surface of the tape was scribed by laser. The magnetization loss was measured by the method using pick-up and cancel coils. We confirmed the effect of striation for reduction of the loss from the measured loss in straight and spiral samples.
