Is it dangerous to live near the high -voltage line of power lines, how to determine its tension? What is the normative distance of the power lines to a residential building?

The power lines are surrounded by large cities almost everywhere, but is it so safe to stay near them for humans?

People have been asking this question since the high -voltage power lines have entered our lives, entangled in their networks of the city and the village. Is it dangerous to live near the power lines? What do sanitary norms and rules say about this, what is the opinion of experts?

Is it dangerous to live near the power lines?

Experts note that staying for a long time in the zone of the power field of power lines Depending on the state of human health, it can have an adverse effect on cardiovascular system, sexual and immune, endocrine and nervous systems, it is possible to exceed the normal level of blood blood cells in the blood, is not excluded and the risk of oncological diseases.

Despite everything, power lines are important enough

A person can feel a constant breakdown, becomes too irritable, immunity is weakened. There is a version about ionization with lines of power transmission particles of dust and impurities near them, which harmfully affects the operation of the respiratory system.
Is it dangerous to live near the power lines? You should stay away from them pregnant and children, people with weakened immunity. It is noted that this category of people may have headaches and pressure increase.

There are countries in which a person subjected to the harmful influence of power lines can change their place of residence to more comfortable in this regard.

It should be noted that electromagnetic fields surround a person not only near power lines. They are radiated by any household and office equipment, mobile phones that are much closer to human brain cells.
How strongly such a field affects a person or an ecological system depends on the power and length of stay in it. In addition, industrial current has a frequency of 50 Hz, and a person perceives much smaller frequencies.
In order to reducing adverse effects of power transmission lines Screeching devices, tools that reduce field strength in the area of \u200b\u200bpower lines can be used.
If the power lines are located quite close to housing, the corners or metal tiles used in the manufacture of roofs are good protection, the most safe in this respect are the walls of reinforced concrete, which weaken the effect of radio waves due to the reinforcing mesh. At the same time, both the net and the roof should be grounded.
By the way, it is important to know that fishing near power lines is strictly prohibited. And if there is a lake with fish near your cottage, and nearby power lines, then refuse to relax with a fishing rod.

If a man lives near the power lines Or often is near the working electrical engineering and feels the malaise that he connects precisely with the influence of electromagnetic fields, it is useful for him to go into environmentally friendly zones located outside the limits of the power lines: to the mountains, on the sea coast, forests.

There are special accredited laboratories that can take appropriate measurements. Their conclusions and conclusions have the power of a legal document. The maximum permissible is considered to be a field of a field of 0.5 kV/m indoor and 1 sq/m - for the development area.

Is it dangerous to live near power lines: determination of tension in power lines

To understand how much it is dangerous to live near the power lines And what is safe distance from power lines, you need to carefully examine it. Minimum voltage is minimal at 0.4 kV, Such lines are equipped with small transparent insulators and five wires.
10-kilos lines They have insulators of much larger (there are only 1-2 of them) and three wires.
The 35-kilo-volume power lines On each of the three insulators is fixed along the wire.
110-kilowed line It has 6 insulators on each of the wires.
And 150-kilo-volume-from 8 to 9. The following are the lines along which electricity is supplied to the substation, their voltage - their voltage - 220 kV, And here the number of insulators reaches 40.
In the most powerful lines (330-750 kV), the number of wires is from two to five, insulators-from 14 to 20.

At what distance you can’t live near the power lines: a safe distance for living

At what distance you can’t live near the power lines:

To avoid risks, the routes of electromagnetic fields that pass such lines are outlined by sanitary protection zones. Their size correlates with the voltage class and is from 20 to 55 meters (In Moscow, these values \u200b\u200bmake up from 10 to 40 meters).
The calculation of the distance is carried out from the wall of the house to the wires. Within these zones, the construction of housing, cottages, public buildings, as well as the location of gardens and gardens, is not allowed.
These values \u200b\u200bdo not take into account the magnetic field surrounding power lines. Therefore, experts recommend, for a complete guarantee of security, it is a tenfold distance from these norms.
For example, the distance around the lines of weak voltage in the radius 100 meters The entire enough sanitary protection zone. The fact is that there are no official data regarding the harmful radiation of power lines, so you should focus on the norms established by documented and your own well -being.

Opinions about how much it is dangerous to live near the power lines, vary. Those who consider them dangerous as confirmation of their innocence give the statistics of deaths in the zones of the passage of high -power power lines. Doctors do not agree with this statement in everything and refer to their indicators and calculations.

Truth, as usual, in the middle: constantly being near the support of the 750-kilometer line, it is quite possible to feel malaise. If contact with the power lines is not constant and the correct distance from it is observed, the body is unlikely to respond to the effect of the electromagnetic field.
