Simplified Conservative Testing Method of Touch and Step Voltages by Multiple Auxiliary Electrodes at Reduced Distance [PDF]
IEEE Transactions on Industry Applications, 2015 Grounding systems (GSs) must be tested periodically in order to maintain the touch voltage (TV) and step voltage (SV) below a safe value in all of the zones of the installation. Measurements of the ground resistance and of the TV and SV are typically done by the fall-of-potential (FoP) method, locating the auxiliary current electrode at remote distance

A Comparative Analysis of Step and Touch Voltages Depending on Two Test Voltage Waveforms [PDF]
Transactions on Electrical and Electronic Materials, 2011 This paper presents a comparative analysis on step and the touch voltages generated by either a sine and a ring wave voltage generator; this analysis was done as a basic study in order to develop a small and lightweight ground meter. A ring wave generator using pulsed power technology was fabricated; an experimental grounding system specified in ...

Control the cost, touch and step voltages of the grounding grids design
IET Science, Measurement & Technology, 2016 In this study, an evolutionary strategy is presented to get the optimal grounding grid design to minimise the design cost, the touch and step voltages of the grounding grid to ensure the economical constraint as well as the safety conditions. The proposed technique is used for one and two‐layer soil.

Smart Touch Voltage Limitation
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021 In modern railway electric infrastructure design there are two major concerns that should be considered as touch voltage and stray current. The first problem is touch and step voltage which endangers human safety even to deathly situations.

An EMTP Extension for Computing Earthing System Transient Step and Touch Voltages
Journal of Energy : Energija, 2022 This paper presents a novel technique for computing dangerous voltages due to lightning transients imposed on earthing system, which is based on the use of the well-known ATP-EMTP software package. Earth surface transient potential distributions, as well as step and touch voltages computations, are performed through extending the widely used EMTP ...
