A Numerical Analysis of Line Equations Considering Corona Loss on a Single-Conductor System and Its Application

Abstract

In this paper, the authors introduce a new digital analysis of the attenuation and distortion of the travelling waves caused by corona discharge on a singleconductor system, which is founded on their surge analyser considering corona loss. Then, applying their theory to the subject of the transient voltage rise of the transmission towers due to lightning stroke on the overhead ground wire, they numerically analyse the subject by a digital computer and discuss the influences of the corona loss on the wire to the tower voltages.
