Grounding resistance, step and touch voltages for a driven vertical rod into two layer model soil
2010 International Conference on Power System Technology, 2010This paper presents a new technique to calculate the grounding resistance (R g ), the touch and step voltages due to discharging current into a vertical rod in two layer soil. The technique is used the current simulation method (CSM). The study of grounding resistance and earth surface potential (ESP) are the outcome of mathematical manipulations of ...

Numerous experiments on animals and on the human body have shown that in order to size a grounding system for an electric installation, it is more correct to apply the allowable values of step and touch currents rather than those of step and touch voltages.

Abstract This paper discusses the development of a new methodology for measurements of earth resistance and touch and step voltages in ground mesh of urban power substations. The main challenge of the work is to find a feasible solution for performing earth resistance measurements from short distances, given that this is the condition actually found ...

Soil moisture variation around the electrical substation grounding system — draining/damping — is usually caused in two ways: (1) seasonal atmospheric changes (atmospheric precipitation, sun, frost) and (2) high intensity and long duration currents flow from the grounding system, e.g.
