Presentation Transcript

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.

STEP POTENTIAL

Equal Potential Zone

HAZARD

Voltage values that equal each other are of the same potential and put you in the same position as a bird on the wire.

110 kv

5 kV Difference

105 kv

100 kv

Never walk or run from a downed power line

HOP or SHUFFLE TO SAFETY.

Keep your feet at the same potential

G.P.R.

Ground Potential Rise

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.
