What is Step Potential
Step Potential What is Step Potential? Step potential is a dangerous electrical phenomenon that occurs when a high-voltage electrical current flows into the ground. This can happen, for instance, during a power line accident or a lightning strike. The voltage difference between two points on the ground can be significant, and when a person steps between these points, they can be exposed to a lethal electric shock. How Does Step Potential Work? When electricity flows into the ground, it spreads outward in all directions. The closer you are to the source of the current, the higher the voltage potential. As you move away from the source, the voltage decreases. However, there can still be a significant voltage difference between two points, especially if they are close together. The Deadly Risk If a person stands near a downed power line, the voltage difference between their feet can be lethal. When they take a step, they are essentially bridging the gap between two points of different ele...
