Measurements of touch and step voltages adopting multi current auxiliary electrodes
Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2000With urban development and buildings growth adjacent to power systems, to choose suitable locations for auxiliary electrodes becomes increasingly difficult for testing the resistance, the touch and step voltages E/sub t/ and E/sub s/ in a grounding system.

Conservative measurements of touch and step voltages by auxiliary electrodes at reduced distance
2014 IEEE Industry Application Society Annual Meeting, 2014Protection against electric shock requires grounding systems that must be designed primarily to keep touch voltage and step voltage below a safe value. The measurement of the ground resistance in a large grounding network requires to place current electrodes at adequate distances.

Measurements of touch and step voltages adopting current auxiliary electrodes at reduced distance
IEEE Systems Technical Conference on Industrial and Commercial Power 2005., 2005The measure of the ground resistance in a large grounding network needs placement of current electrodes at a great distance. In urban areas, where buildings' growth is adjacent to a power system, choosing suitable locations for auxiliary electrodes becomes increasingly difficult since rigorous ground resistance measures can impossibly be made.

Thevenin source resistances of the touch, transferred and step voltages of a grounding system
IEE Proceedings - Generation, Transmission and Distribution, 1999The source resistances for surface voltages (touch, transferred and step voltage) are considered. It is proved that the source resistances of the touch and transferred voltages are the same, given by the grounding resistances between the feet of a human and the grounding system.

Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2012
This paper describes the analysis technique of risk voltage around grounding electrode by new touch and step voltage measurement methods. We have analyzed three techniques for risk voltage measurement, such as footprint-electrode method, test-probe method, and simulated-personnel method.

TOUCH AND STEP VOLTAGE HAZARD ANALYSIS
This article analyzes the risks associated with electric shock, specifically focusing on the effects of touch and step voltage, which can lead to severe injury or death. Citing international studies, the research confirms that older individuals typically exhibit a body resistance between 1000-2000 Ω, with exposure to 230 V potentially causing dangerousE.S.

Study of Step and Touch Voltages in Resistive/Capacitive Ground due to Lightning Stroke
The 2006 4th Asia-Pacific Conference on Environmental Electromagnetics, 2006This paper aims to calculate step and touch voltages around transmission line tower foot due to lightning strike to the transmission line tower top and injecting the lightning current into resistive/capacitive ground. The transmission tower foot is modeled as hemisphere electrode impeded in the ground with specific conductivity and permittivity.

Step and touch voltages near wind turbine grounding during lightning strokes
International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2012In this paper we analyze the transient step and touch voltage distributions near wind turbine grounding system in case of direct lightning strokes. Two models of the grounding system geometry are considered: the usual conservative model that takes into account only basic grounding electrodes, and integrated model including foundation reinforcement as a

Comparison of touch and step voltages between IEEE Std 80 and IEC 479-1
IEE Proceedings - Generation, Transmission and Distribution, 1999A comparison of the safety criteria of two widely accepted standards, i.e. the IEEE Std 80 and the IEC 479-1 is proposed. The two standards differ in their definitions of permissible body current and body resistance. Another difference is that the IEC 479-1 does not provide guidance on human feet/soil contact impedances.

A Thevenin equivalent approach for touch voltage and step voltage
2000This paper describes numerical algorithm for accurate computing of the touch voltage and step voltage. The algorithm is based on the Thevenin equivalent and grid model of the human's feet.It is practically to use this accurate approach only for some very important points on the earth surface because Thevenin equivalent circuit is valid only for a given
