Development of a single-phase 30m HTS power cable

Characteristics of the joint mini-model high temperature superconducting cable

“…8 shows the measured AC loss as a function of transport currents for the jointed mini-model HTS cable and calculated result by the Carr and Magnusson expression. The rectangular indicates the measurement and the half of black circle indicates theory of the AC loss obtained by Eq (5). The difference between the theory and measurement is thought to be caused non-uniform current of HTS tape in the mini-model cable, however the measurement data agree well with theory when transport current is less than 1300 A peak .…”

“…Specifically, superconductive joint technique is needed to obtain interconnections between various parts of a superconducting apparatus such as superconducting subunits, bus-bar, current lead and joint box of HTS cable [3]. In particular, the joint box is necessary to apply the HTS cable to the long power system [4][5].…”

A study on the improvement of protective relay system for the utility application of HTS power cable

“…A research group in Korea has completed the development of HTS power cable system of 22.9 kV/50 MVA, 3 phase 100 m as a part of the 21st Century Frontier R&D Project supported by the Ministry of Education, Science and Technology [5][6][7]. However, before the installation of the HTS power cable into a utility grid, it is necessary to confirm reliable performances and stability during both normal and transient states.…”

Transposition-Based Connection Scheme and Joint Box Concept for a Tri-Axial HTS Power Cable

“…HTS power cables have already been connected to real utility grids [1]. Of these, the tri-axial HTS cable is expected to most effectively solve upcoming power issues, such as the increasing demand for electricity and the limited space of power corridors.…”
