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.
Equal Potential Zone
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
105 kv
5 kV Difference
100 kv
Never walk or run from a
downed power line
Ground Potential Rise
95 kv
HOP or SHUFFLE TO SAFETY.
Keep your feet at the same
potential
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.
