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 ...

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 ...
