Abstract

A new prediction model of the ground distributed parameters for the transient analysis of multiconductor lines is proposed, which applies in a wide frequency range and/or high ground resistivity. The obtained formulation, basing on a rigorous procedure, is simple to handle for implementation in a computer code. The comparison between the developed approach and the Carson model is carried out in order to define analytically the differences concerning the expressions of the line parameters. Both the models are applied to the computation of the transient voltages of a power line excited by a current source or an EMP-plane wave
