Step and Touch Voltage Distributions at GSM Base Station during Direct Lightning Stroke
2008 International Conference on High Voltage Engineering and Application, 2008One of the tasks of earthing system is to ensure safety for people during various fault conditions. The objective of this paper is to provide knowledge about the actual step and touch voltage distributions in and around a freestanding base station for mobile communications during direct lightning strike into the communication tower.

Wind farm grounding systems design regarding the maximum permissible touch & step voltage
2012 11th International Conference on Environment and Electrical Engineering, 2012Nowadays Wind turbines are used over a wide area as they are environmentally favorably means to product energy without emissions and moreover the fuel is wind which is free for use. Wind turbines are often installed in mountainous area where the soil resistivity and isokeraunic level is high.

Progress in step and touch voltage equations of ANSI/IEEE Std 80-historical perspective
IEEE Transactions on Power Delivery, 1998This paper describes the evolution of safety criteria and the development of basic formulae for evaluation of the step and touch potentials in AC substations, from 1961 to the present time. Refinements proposed for the 1996 edition of ANSI/IEEE Std 80 are presented in a broader context of the continuing development of this popular IEEE Guide.

Simplified conservative measurements of touch and step voltages
1999 IEEE Industrial and Commercial Power Systems Technical Conference (Cat. No.99CH36371), 2003Protection against electric shock requires grounding systems that must be designed primarily to keep touch voltage (E/sub t/) and step voltage (E/sub s/) to a safe value. Testing of the efficiency of a grounding system is mandatory to verify the capability to satisfy the protection requirements at the end of the construction and periodically in the ...

A Practical Probabilistic Method to Evaluate Tolerable Step and Touch Voltages
IEEE Power Engineering Review, 1984A simplified probabilistic method to calculate the risk of the human body withstand voltage to be exceeded by step and/or touch voltages appearing during abnormal system fault conditions is presented in this paper. The determination of density probability functions and cumulative distributions are done by using characteristic parameters of well known ...

A new method and instrument for touch and step voltage measurements
IEEE Transactions on Power Delivery, 1994This paper describes a new method and instrument for measuring touch and step voltages near a grounding system, for example in and around a substation. The hardware, software, and testing procedures are an extension of the smart ground multimeter, developed under EPRI sponsorship.
