Inge CuCThe increasing demand and the benefits of electricity energy have led to the creation of huge power plants, so high voltage substations are necessary for electrical energy. Installing different small power plants to prevent consumption in different parts of a country requires reservation units and high costs for repairs, maintenance and fueling.

Field Measurements Of Touch And Step Voltages
IEEE Transactions on Power Apparatus and Systems, 1984This paper presents the study of a measurement technique for touch and step voltages and the results of measurements obtained inside and outside substations. Details of a low-voltage and a highvoltage method of current injection are given. Setups for measuring the shock touch voltage and shock step voltage are characterized, in which the effect of foot

An alternative approach for touch and step voltages measurement in high-voltage substations
Electric Power Systems Research, 2016Abstract This paper presents the study of a measurement technique for touch and step voltages. In essence, we elaborate an approach which is very similar to the measurement of the grounding system impedance. In addition, the main focus is on the measurements at energized substation where different types of coupling between the test leads, grounding ...

Design of permissible step and touch voltage with SIMULINK and MATLAB guide
2018 26th Signal Processing and Communications Applications Conference (SIU), 2018In this work, the permissible step and touch voltage are designed in MATLAB SIMULINK. The simulations were carried out in accordance with the IEEE Std 80-2000 standards. The effects of the specific resistance of the material covering the surface, the cleaning time of the short circuit current and the specific resistance of the soil to the permissible ...

Step and touch voltage – an update for 2004
Australian Journal of Electrical and Electronics Engineering, 2005Hazardous step and touch voltages arise in a variety of high voltage electrical installations, and there are a number of different industry publications which publish acceptable step and touch voltage limits. This paper sets out the derivation of step and touch voltage limits based on the work of Dalziel and Biegelmeier and Lee, and AS/NZS 60479.1 ...
