Step Potential definition

Step Potential means the voltage between the feet of a person standing near an energized grounded object. It is equal to the difference in voltage, given by the voltage distribution curve, between two points at different distances from the electrode. A person could be at risk of injury during a fault simply by standing near the grounding point.
Step Potential means difference of voltage between the steps of an Operator, human being or animal coming in contact or operating electrical facilities of a distribution company;
Step Potential means the maximum value of potential difference possible of being shunted by a human body between accessible points on the ground separated by distance of one pace which may be assumed to be one metre;
