How to get from step voltage

Only once included in the circuit through which the current passes, the person becomes susceptible to defeat. The reasons for inclusion in the chain can be different: inadvertently touching the bare wire, using the body of the appliance with damaged insulation, touch the conductor under tension.

Much less is known about the risk of electric shock when hit in the area of so-called "stepper voltage". The so-called voltage, which occurs when the open and in contact with the ground wire of a power line energized.

If the line is not turned off, the current continues to flow through the wire. The reason for this is the fact that the ground conducts electricity. Any point on the earth's surface in the zone of the drop wire in this case carries some potential. This potential is greater, the closer to you the point of contact of the wire with the ground.

When the feet of the person touching two points on the earth's surface that have different potentials, the person is under the influence of electric current. The wider the step, the greater the potential difference and the more likely that will happen an electric shock.

The value of the stepper voltage is directly dependent on the resistivity of the soil cover, the strength of the current flowing in this circuit. The largest magnitude of the step voltage is at the approach to the fallen wire, the minimum voltage occurs at a distance more than twenty meters from the wire.

When injected into the area of the stepping stress in humans observed muscle twitching in the legs that may cause you to fall. Step voltage, when the fall ceases to act on the person because it is formed another path for current flow from hands to feet). Here is what creates a deadly danger.

Once in the zone of action of the stepper voltage, should leave her very short steps, and even better – jumping on one leg.

If you see a wire lying on the surface of the earth, nor in any way to it do not approach. The affected area may be located within a radius of eight meters around the place of contact of the wire with the ground. Wet soil increases the space where it is possible to lose.

It is forbidden to approach on the ground wire or a person lying in the affected area. You can't tear the soles off the ground to make the strides or run. The movement is exclusively the "goose step". Never touch the person affected by electric shock without first de-energized the power line.
