Summary:This paper introduces an analytical formula for calculation of the maximum step voltage at a substation grounding grid, based on a new theoretical analysis method. The accuracy of this formula is checked by the results obtained from both the computer program calculation and the model test. Evaluations of the formulae commonly used to calculate step voltage in various countries are also given.
