Abstract In this paper the earth structures of four cities are analysed on the basis of the measured soil resistivity and the characteristics of a grounding system is examined. As a result, it is revealed that the soil resistivity has an effect on touch voltage and step voltage, which are directly related to safety, as well as ground resistance.
