How is step potential defined?

Step potential refers to the voltage difference experienced by a person standing near an energized, grounded object. This phenomenon occurs when there is a voltage gradient in the ground due to a fault or when an electrical current travels through the earth. When a person is standing with their feet a certain distance apart, a difference in electric potential can be present between their feet due to this gradient, leading to the risk of electrical shock.

Understanding step potential is crucial for linemen and those working with electricity because it illustrates the dangers associated with standing near energized equipment or conductors. Safety practices, such as maintaining safe distances and using personal protective equipment, are critical to mitigate these risks while working around high-voltage areas.

The other definitions, while related to electrical contexts, do not accurately capture the essence of step potential as it specifically pertains to the scenario of a person standing near an energized object.
