In this paper we present the results of tests for high-T/sub c/ superconducting (HTS) power cables and the analysis of an HTS power transmission system in Korea. Prototype HTS cables have been constructed using Bi-2223 based Ag-sheathed HTS tapes. The prototype cable has been tested at 77 K with DC currents. Results shows that the cable carried up to 730 A DC and the authors analyzed the feasibility of a HTS power transmission system in the Seoul area in Korea. According to the analysis results, the HTS power system can be reduced by 5.2%/spl sim/9.7% of the underground transmission lines compared to the conventional cable system in Seoul, Korea and the HTS power cable is feasible in future power systems.
