Modeling of overhead transmission lines with segmented shield wires for signal attenuation calculation in power line carrier systems

Abstract

This paper presents modeling methods for overhead transmission lines with segmented shield wires, as well as signal attenuation calculation for different coupling methods for use in power line carrier (PLC) systems. The purpose of this paper is to present a generalized method to model transmission lines with segmented shield wires, along with steps for signal attenuation calculation in the phase domain for different PLC coupling methods. Electromagnetic Transients Program (EMTP) simulation results for signal attenuation are provided for comparison with the generalized model calculation results.
