Auxiliary Electrode Arrangements’ Effect on Earth Resistance Measurements with Fall-of-Potential Method
(full text in English)

Balazs SMOHAI, Jozsef LADANYI
Abstract
This paper presents a simulation study in connection with earth resistance measurements using the fall-of-potential method. The main goal is to introduce and assess the effect of the auxiliary electrode distances, arrangements on the measurements’ accuracy. The regulations, the practice, and numerous other factors have been taken into account. The results are presented in case of a substation and a transmission line tower grid, with different soil structures and potential probe-current electrode layouts.
Keywords: substation, transmission line tower, resistance to earth, measurement error, fall-of-potential method, simulation, site measurement
