The application of power line carrier (PLC) to utility transmission systems can provide a reliable means of communication over short and long distances. However, PLC performance is dependent upon an adequate signal-to-noise ratio at receivers. The calculation of path attenuation of signals on the transmission line can be complicated, especially in branched networks. The calculation method described here is based on the construction of an impedance matrix using multi-phase, long line pi-equivalents for transmission lines. The method can predict PLC attenuation for a variety of network topologies and is demonstrated for two cases.
