Abstract

Exact knowledge of the impedance is a key aspect for power line modem development as well as for modeling channel transfer characteristics of power distribution networks used for low-frequency power line communications (PLC). Therefor we present an approach for precise impedance determination at the low-voltage grid and results we obtained from a measurement campaign. Furthermore we investigate the accuracy of modeling channel transfer functions with two-conductor transmission line theory using actually measured impedances.
