This paper presents an approach to model the
transfer function of a four-conductor power line cable for
power line communications. The model is derived from
multi-conductor transmission line theory by taking into
account all couplings between the conductors. The model
allows one not only to determine the transfer function, but
also the interference characteristics of that transmission
medium. The transfer function for a straight line without
branches is obtained first, and then crosstalk is derived.
Finally an N-branch network is simplified based on a
generalization of the transmission matrix method. The
transfer characteristics of the equivalent network are
derived in a similar way as for a straight line.
