Coupling Currents distribution and Losses of HTS Mult-filament round wires by using FEM

The round HTS wire is easier to handle than the rectangular HTS tape. This paper describes the coupling losses of the round HTS wires by finite element method. Effect of filament arrangement and filament size of the round HTS wire are considered. Three types of filaments arrangement, one and double layer radial filaments and Multi-filament, are considered. Calculation results show that coupling losses of the one layer filaments round HTS wire vary only a little with the direction of external magnetic field.
