Finite element computation of field, losses and forces in a three-phase gas cable with nonsymmetrical conductor arrangement

A finite-element field computation for a three-phase gas-insulated power cable is presented. The phase conductors carry sinusoidal currents in a steady-state and balanced condition. Both symmetrical and nonsymmetrical conductor arrangements are examined, taking into account the real geometrical and physical cable properties. Losses, forces, inductances, and current density distributions are calculated. Comparison is made with theoretical and experimental results given in the literature
