Abstract

The main objective of grounding electrical systems is to provide a suitably low resistance connection to the substation above it the low resistance is needed to limit the potential rise of the substation from the potential of the surrounding earth. This potential rise must be limited so that there is no danger to anyone standing on ground but touching, for example, the substation fence. In order to ensure that the ground potential rise, and touch and step voltages, an accurate soil model are needed to perform calculations that ensures that the resistance of the grounding grid through the earth is sufficiently low. This soil model comes from the tested soil structure at the proposed grid location. This paper provides a literature survey of the various soil testing methods and soil modeling. The paper is divided into 2 parts: Part 1 describes the current soil measurement techniques; Part 2 examines the model construction of the uniform and two layer soil structures, and the short comings of the current modeling techniques.
