An alternative approach for touch and step voltages measurement in high-voltage substations
Electric Power Systems Research, 2016 Abstract 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 ...
