Abstract

A theoretical model for determining the signal strength of communication signals on three-phase power distribution lines is described. The purpose of this model is to aid in the design of distribution line carrier systems. Per-unit length impedance and admittance matrices are calculated for a particular transmission line geometry. The elements of these matrices are influenced by the skin effect for stranded conductor cables. Voltage and current are plotted versus distance from the source for all three phases and these plots are compared with measurements made by J.D. Suh (1988) and J.D. Suh et al. (1990). It is concluded that the proposed theoretical model is useful for predicting voltage and current profiles on distribution lines
