Characteristics of PLC Channels over High Voltage Power Cables and Mixed Cable-Overhead High Voltage Power Lines

摘要

This article discusses the characteristics of high voltage power line carrier channels over underground cables and mixed cable-overhead high voltage power lines. It shows which modal parameters underground cables have and how junctions of overhead power lines with power cables influences to the parameters of PLC channel. The most difficult and interesting scenario when underground cable has sheaths transpositions or/and sheaths earthling at one end of the line is covered.
