Abstract

3-D finite element analysis of current distribution taking account of the nonlinear E - J characteristic is carried out. In order to study the ac loss of multi-layered HTS power cable, the analysis region is considerably reduced by modeling spirally wound superconducting tapes as conductors having an anisotropic conductivity and using the periodic boundary condition. By using this model, the effect of the twist pitch on the current distribution of multi-layered HTS power cable with a shield layer is illustrated and the structure with low ac loss is discussed.
