SHIELDING FROM INDUCTIVE EFFECTS OF TRANSMISSION LINES IN THE SYSTEM OF TWO UNDERGROUND CONDUCTORS

, and .
(1981)

Abstract

This paper presents the method of calculation of the potential excited by inductive effect of a transmission line, along an infinitely long underground conductor, buried in the vicinity of another ground return circuit, which fulfils the role of a shield. The inductive as well as conductive coupling existing between these two ground return circuits are taken into account. The reduction factor allowing for both kinds of interaction between a protected conductor and a shield has also been determined. The technical application of the method presented is ilustrated by examples. The effect of variations in parameters of the system is considered.
