What does a higher value in step voltage indicate?

A higher value in step voltage indicates a potential increased risk of electric shock. Step voltage is the difference in electric potential between two points on the ground, typically measured as you move away from an energized source. When this voltage is high, it signifies a significant electrical potential difference, which means that if a person were to contact two points at different potentials, they could receive an electric shock. This situation often arises in scenarios with inadequate grounding or bonding, where the electrical energy is attempting to dissipate through the earth but encounters resistance. As the step voltage increases, so does the danger to individuals who may inadvertently create a path to ground, leading to a risk of severe injury or fatality from electric shock. Understanding this relationship highlights the importance of proper grounding and bonding practices to ensure safety around electrical installations.
