Evaluation of cross-talk in power cables by use of 3D finite element computations

Finite element computations are presented, studying the
effect of cross-talk between cable elements of different lay
lengths. 3D computations with twisted conductors and
screens are compared to the more traditional 2D crosssection
approaches. Current flow in screens and
impedances of cables are obtained. The results show that
for the cable studied the calculated system parameters
greatly depend on the approach chosen.
