A tri-axial HTS power cable has been proposed and developed to reduce the number of HTS wires because it has copper shield instead of HTS shield. However, it has a drawback which is an inherent imbalance problem due to an asymmetry configuration in the cable.
The authors designed a 22.9 kV/50 MVA class tri-axial HTS cable. The inherent imbalance problem of the three-phase currents in the tri-axial HTS power cable has been minimized through the adjustment of pitches and radii of each layer. An FEM analysis program and a power system analysis program were used to analyze the characteristics of the designed tri-axial HTS power cable. The AC loss and magnetic characteristics of the designed cable were analyzed according to magnitude of operating currents. The design results of the tri-axial HTS power cable are discussed in detail.
