Web21 May 2024 · Step Potential is the voltage between the feet of a person standing near an energised earthed 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 connected object.
