Conductor pitch effect on an eddy current loss of the superconducting power cable using the disassembled cable 'N' data

摘要

The origin of the difference between measured AC loss and that of the short sample test has been studied. The axial field due to disordered pitch of conductor and shield tapes has a trivial effect on the eddy current loss in the stabilizer. The displacement of the current direction on the conductor from its lay angle makes comparable eddy current loss.
