Digital transmission performance of carrier channels on distribution power line networks

The analysis of the transmitting features of wire-to-ground and wire-to-wire carrier channels on power distributionnetworks is performed both in the frequency- and in the time-domain. A new formulation of the lossy ground return parameters isconsidered, which applies in a wide frequency-range and in case ofpoorly conductive soil. The sensitivity of the frequency-spectra andlongitudinal profiles of the transmitted voltages to the distributionsystem configuration, load termination and ground resistivity isinvestigatedThe eye-diagram approach is used in order to ascertainthe transmission quality of carrier channels on tree- and mesh-typenetworks, in case of high capacity digital signals.
