Abstract

This paper is aimed at providing the substation design engineer, to accustom with methods of earth resistance measurement and soil resistivity measurement using DC Source of higher current magnitude. In most of the cases, the measurements were conducted using conventional methods by adopting earth testers. However, the knowledge gained by experience from time to time has resulted in the adoption of High Current DC source in measurements especially for an electrode station of HVDC substation. These measurements are of more realistic in nature. This paper discusses the methodology adopted for the earth resistance measurement using dc source of higher current magnitude at an electrode station of HVDC substation.
