| Abstract | Unequal current distribution inside underground cables in close proximity causes unfavorable induced voltages and losses in their sheaths. Because of the problem complexity, most previous researchers in the field have not modeled the skin and p~oximity effects with sufficient accuracy. In this paper, a new technique is presented for tackling the eddy current problem of non-magnetic multi-conductor systems. The technique utilizes an efficient impedance matrix formulation, which yields accurate current distribution assessment. Applications to a set of test cable systems are also presented in the paper to demonstrate the usefulness of the proposed technique. |
