Abstract

Prediction models of the electromagnetic interference generated by carrier channels on multiconductor power distribution lines with nonradiating terminal loads are presented. The proposed formulations are addressed to the evaluation of the radiated field components in a wide frequency-range, by including the effects of the lossy ground plane and removing the hypothesis of unidirectional current propagation. The validity of the infinite-length approximation and of the complex image approach are investigated, with reference to different line-configuration, in case of wire-to-ground and wire-to-wire signal transmission
