Models for optimization and AC Losses Analysis in a 2G HTS Cable

Finite element method (FEM) for both linear and nonlinear cases is widely used solving time-dependent problems related to the geometrical configuration of electrical HTS devices AC losses. This paper presents our FEM models in development cables. Transient 3D have been developed optimization coaxial triaxial 2G In these models, only magnetic materials are considered. The transient 2D model was calculation losses cables made from tapes. layer tape has strong nonlinearity between resistivity current density requires careful modeling. Also, it important determine parameters an empirical expression that describes critical dependence vector field its non-uniformity across width.
