摘要：

The article presents a methodology for calculating the step voltage on the ground surface above the grounding grid of an MV/LV substation. The calculations are performed by using the interpolation method based on the knowledge of the electric potential distribution. The electric potential distribution was determined for the grounding grid model using the finite element method in ANSYS program. The interpolating relationship of two variables allows the calculation of step voltage for any location of human feet.
