Description

The high temperature superconducting (HTS) quasi-isotropic conductor with high current capacity and quasi-isotropic performance is expected to have a wide application. AC loss is one of the major obstacles. This paper aims to study the AC loss of the quasi-isotropic conductor stacked by the second generation (2G) HTS tapes and copper tapes at 4.2 K. In order to fully understand AC loss characteristics of the stacked-tape conductor, an efficient 3D finite element method (FEM) model based on T–A formulation is adopted. This model can be adopted to handle the simulation challenges of HTS tapes with high aspect ratio and overall understand AC loss in the twisted quasi-isotropic conductor.
