Cable analysis using 3D modeling and simulation technology
NKT in Sweden uses numerical modeling to investigate electromagnetic fields and calculate armor losses in 3D cable designs. The modeling results were validated with experimental measurements in order to be able to carry out design analyses with the aid of simulations.
