Abstract

In case of manufacturing the applied superconducting machines using High-Tc superconductor (HTS) such as SMES, MAGLEV, and superconducting generator, superconducting joint is very important because they need very long tapes. For this reason, the investigation of AC Loss of jointed tapes should be considered as well as that of the AC Loss of jointless tapes, and so we investigated the tendency of AC Loss with superconducting joint, and compared the AC Loss of jointed tapes with that of jointless tapes. In this paper, the AC Loss in BSCCO-2223 silver (Ag) sheathed tapes was measured by using four-probe transport technique at 77 K. Firstly, it was shown that the experimental measurement of AC loss in the tapes agree well with the calculated values provided by Norris equation. Moreover, it was shown that the AC loss depends on amplitude of transport current. Finally, it was shown that the AC Loss depends on joint resistance and index n.
