The electricity thing is very, very useful, no doubt. Bygone 20th century era of electrification. Indeed, everywhere you look kin, almost everything has a power source and through this work. But at the same time, electricity is a serious danger, because it is not visible to the eye, as, for example, fire, and may not be noticeable until with him do not come into contact. One of the most dangerous manifestations of electricity is a step voltage . Learn safety techniques.
Instruction
Difficulty level: Difficult
step 1
Step voltage may occur when the bare end of the wire under tension falls to the ground. This happens when there is a broken wire, which, for example, existing power lines (transmission lines) or contact the network near the railway. The earth is a conductive element, therefore, the path of current flow does not stop. If people at this time will be within range of the electric field near the wire, it will become a part of an electric circuit, because the human body is also a conductor.
2 step
The definition of voltage step sounds like a potential difference between two points of contact with the ground. Contact ragged wire under tension with the earth, each point on the earth's surface around the contact areas carries a certain potential. Farther from the place of contact of the wire with ground, the potential below. If people were near the wire, his legs become conductors that touch of ground points with different potentials, and therefore produces an electric current. The larger the potential difference, i. e. farther apart legs, the more voltage
3 step
If it happened that you were near thorn wire, remember to go away you SMALL STEPS so as not to create a potential difference between limbs. Closer to the ragged wire CANNOT! Danger zone with the presence of voltage is within 8-10 m about a point of contact with the ground. In addition, the soil may be wet, that will be an additional provodnikovym effect and will increase the area potential.
step 4
For all employees who deal with high-voltage wires should know the safety rules. But for ordinary people, it is very useful to know not to get into a dangerous situation.
Be careful!
