The continuity of shield wires is often broken for losses reduction purposes in high voltage transmission lines. The accurate simulation of the effects of this practice on power line communications in multiconductor transmission lines is performed in the time domain by means of a finite-difference method. Losses in wires and ground are accounted for by means of transient per unit length parameters and recursive convolution. The method overcomes most of the usual problems encountered by frequency-domain modal analysis techniques.

Abstract
The continuity of shield wires is often broken for losses reduction purposes in high voltage transmission lines. The accurate simulation of the effects of this practice on power line communications in multiconductor transmission lines is performed in the time domain by means of a finite-difference method. Losses in wires and ground are accounted for by means of transient per unit length parameters and recursive convolution. The method overcomes most of the usual problems encountered by frequency-domain modal analysis techniques.| File | Dimensione | Formato | |
