摘要：
The propagation properties of overhead three-phase cables are usually analysed assuming that the pipe conductor establishes a perfect shielding between the inner conductor set and any outer conductor, i.e., the power cable is assumed as an isolated system. The influence of a lossy ground plane in the neighborhood of the cable is examined in this paper. The propagation parameters for both approaches are compared - significative differences being found to exist, in the zero mode, at low working frequencies. © 1990 IEEE
