Modern house is just crammed with various electrical appliances, and even more so a private house. The life support of country houses, dachas and cottages sometimes depends entirely on electricity. Therefore, even an ignorant person in electrical matters understands that special security measures are needed here.
Grounding in a private house is one of the most important measures to protect a person from electrical shock. If you neglect the basic safety measures, saving on high-quality grounding, sooner or later a situation may arise in a private house in which, touching the refrigerator case, someone will receive an electric shock. This happens when the insulation is damaged. However, a lightning strike can often cause failure of expensive equipment or a fire in residential buildings.
Lightning protection of buildings, as well as grounding in a private house, is an essential element of electrical safety. The figures also speak in favor of the need for lightning protection: about 20 million thunderstorms occur on Earth every year, which is about 50 thunderstorms per day.
Common grounding in a private house is part of its lightning protection. Otherthe components of the system are lightning rods and conductors that divert current. A lightning discharge, falling into a lightning rod through a conductor, goes into the ground - this is the general principle of external protection against lightning. There is also internal protection - SPD. Lightning current, when exposed to an object, can cause resistive or inductive couplings, which lead to overvoltage in the network. It is from this overvoltage that the SPD protects the building. Depending on the nature of the lightning strike - direct or indirect - there are several classes of such devices that reliably protect the house and its residents from the effects of overvoltage. But back to external lightning protection.
It is customary to distinguish two types of it - passive and active. Passive, figuratively speaking, waits for a lightning strike and simply diverts the discharge to the ground. Active lightning protection takes the initiative - intercepts the discharge and "neutralizes" it, also taking it to the ground. An active lightning protection system is also called a system with preemptive streamer emission. The difference between passive and active protection lies in the lightning protection elements themselves. Passive uses rods, mesh or cable stretched between two supports. This is the most common and traditional way to protect against lightning in private homes. In addition, it is relatively cheap. The system of active protection against lightning uses a lightning receiver - an ionizer, which reacts to an increase in the intensity of the electric field. During a thunderstorm, a magnetic field is formed between the earth and the sky, due to which this ionizer works.
Dignityactive lightning protection of buildings are as follows:
- Large, compared to passive, protection area - this allows you to organize lightning protection of a whole group of buildings;
- Durable construction to withstand repeated discharges
- Reliable operation in any, even extreme weather conditions
- Full autonomy of work
- Easy installation and maintenance
- Antenna mast lightning arrester safety
- Aesthetic appearance.
The safety of people living in a building can only be ensured if grounding in a private house was carried out in conjunction with lightning protection, whether active or passive.
