The modeling of transfer characteristics of low voltage power distribution networks for PLC requires the knowledge of the electrical parameters of the cables comprising these networks. In this paper, a method has been developed for characterizing the power line cable parameters. As a complement to many existing approaches, we estimate the cable parameters from a set of easy measurements. A multi-conductor powerline cable has multiple, coupled propagation modes with corresponding primary parameters, even if the propagation speed of those modes is nearly the same. Based on multi-conductor transmission line theory, we propose a practical measurement approach to derive the important parameters separately. With the parameters, the transfer function of any length of the same kind of cable can be obtained easily. The approach is validated by comparing the computed transfer function of a power line cable with the directly measured one.
