When an energized line makes contact with ground the earth becomes hot and the voltage dissipates in concentric circles away from the initial contact point.

Voltage values that equal each other are of the same potential

and put you in the same position as a bird on the wire.

Step Potential is the voltage value between the span of one step. Each foot is referenced

to a different potential or

voltage. This difference of

voltage is called a Step Potential

Hazard.
