Do-it-yourself lightning protection for a private home, country house and more
Advice from professionals on lightning protection
The destructive power of lightning is quite understandable: its current reaches two hundred thousand amperes at a voltage of up to one hundred thousand kilovolts. Moreover, there are cases when several lightning strikes in the same place within one and a half seconds. And even one lightning strike on a structure without a lightning rod is enough to make it burst into flames like a candle. Despite this, small house Protecting against lightning is quite easy.
A conductor is stretched over the roof ridge (at a distance of at least 25 cm from it) - a steel wire 5-6 mm thick (Fig. 1 on page 16). On wooden beams to which it is attached, vertical lightning rods up to a meter high are installed. chimney A steel cap, wire “plug” or loop connected to the conductor will reliably protect. The same conductor goes down the shortest route along the wall of the house and is connected to the ground. If the length of such a lightning rod is more than ten meters, then it should be grounded on both sides.
Lightning most often strikes roof ridges, gable edges, dormer and skylights. Therefore, the conductor can be laid over such protruding places, attached directly to a roof made of tiles, slate, or mounted on wooden pins or a solid block on a roof made of shingles, roofing felt and other combustible materials. Such a lightning rod is grounded at several points. Wooden parts painted with oil paint.
A house covered with iron will be completely safe if you ground its roof three or four times every 10-15 m around the perimeter. How to attach the grounding is shown in Fig. 2.
Easy to manufacture and lightning rod. With a height of 5 m, counting from the ridge, it can protect a house 15 m long and 7 m wide. Install the lightning rod on a pole 10-15 cm thick, nailed to the rafters in the middle of the roof or dug in next to the house. You can also strengthen the lightning rod on a tree growing near the house.
He is tied to the trunk above the branches soft wire 02-Zmm every 2-3 m. If the house is located closer than 5 m from the tree, then a conductor is laid along its wall, connected to the same ground as the lightning rod (Fig. 1).
The upper end of the lightning rod is made of wire of the same diameter as the rest of its parts (or larger - up to 14 mm, steel strips, angles or pipes with a cross-section of 50-60 mm2. The pipe at the top is flattened or welded into a cone, and a loop is made from the wire, securing by twisting it or using a wire bandage (Fig. 3).
Grounding can also be made of wire, but it is better to make it from steel pipes, for example, water pipes, 040-60 mm, steel strips, corners and other material with a cross-section of at least 50 mm2. Grounding is laid to a depth of at least 80 cm (the deeper, the better). In the simplest case, a wire or metal strip several meters long is laid in a ditch. You can drive two or three piles of pipes or angles into the ground so that their upper end is at a depth of 80 cm. The piles are connected by a horizontal bus made of steel strip or wire, to the middle of which a lightning rod is attached (Fig. 4).
If the soil is dry, sandy and does not conduct electricity well, then the grounding should be backfilled charcoal, mixed with table salt(about 0.5 kg of salt per bucket of coal). This will greatly reduce the soil resistance: coal - good guide, and salt is hygroscopic.
Grounding should be located at a distance of at least 5 m from paths and passages.
The lightning rod is strengthened on wooden walls and poles with staples or clamps nailed at a distance of one to two meters from each other. It is useful to place insulators made from a piece of rubber hose under the clamps. Conductors must be laid so that there are no loops or sharp corners on them, otherwise they may be torn apart by the forces generated by a lightning discharge. They are closed to a height of about 2.5 m from the ground steel pipe, corner or wooden box.
Methods for connecting lightning rod parts are shown in Fig. 5. The most reliable are welding or soldering, but you can also use twisting, bandage connection, special compression or overlap connections using bolts and rivets.
Contacting surfaces must be well cleaned of paint, dirt and rust. The joints (except welded ones) are wrapped with insulating tape, then with thick fabric, secured with thin wire or twine, and the whole thing is painted over without breaking the contact. The paint protects well from oxidation. There must be reliable electrical contact between all parts of the lightning rod.
Every year, before the onset of thunderstorms, parts of the lightning rod and their attachment points are inspected and, if necessary, they are replaced and painted.
Once every three years, check the serviceability of the connections, clean the contacts, tighten loose connections or replace them.
Once every five years, the grounding electrodes are opened, the reliability of their connections and the depth of corrosion are checked. If the cross-section of a rusted part has decreased by more than one third, it should be replaced.
IN Lately We are increasingly faced with situations where lightning strikes houses and, due to the lack of appropriate protection, a fire occurs. To prevent this from happening and to protect yourself, you can make a lightning rod with your own hands.
Moreover, such a device will be quite functional and productive, if, of course, it is installed correctly. It is worth saying that although the lightning rod has enough simple design and if you have free time and the necessary materials, anyone can make it, however, you will need to take into account many factors to determine the correct installation parameters, since it is important not only to have protection for your home and electrical appliances, but also to be confident in its correct functioning.
How does a lightning rod work in a country house?
A lightning rod is a special installation that attracts the electric charge of lightning and redirects it from the house through a conductor to the ground. Thus, lightning will not cause any destruction or harm. The lightning rod consists of two blocks:
- external;
- internal.
The outdoor unit is a current collector (lightning rod), connected to a current conductor (down conductor), which together act as a receiver and distribution of lightning charge, as well as a ground electrode, which dissipates this charge in the ground.
The indoor unit will protect your home from power surges and, therefore, prevent failure of electronics. Probably everyone has heard that if the electric charge of lightning is strong, then all the electrical appliances in the house burn out.
So there is another reason to make a lightning rod.
Lightning rod design rules
For the right choice diagrams for the installation of a dacha lightning rod, it is first necessary to study the structure of the building and, in accordance with the “Instructions for the installation of lightning protection of buildings and structures” (Instruction RD 34.21.122-87), determine the required level of protection. Low and small in area private houses usually belong to lightning protection category III.
Effective lightning protection is one that reliably protects the building and everything inside it from direct lightning strikes and from its secondary discharges in electrical networks. A country lightning rod is usually a lightning rod, which is connected to grounding using a down conductor system.
Lightning rod
A device that directly receives a lightning strike is called an air terminal. This is the most noticeable and significant element of an industrial or country lightning rod design. There are rod, cable, and mesh receivers.
The most popular and famous thanks to Benjamin Franklin is the lightning rod, which is metal pin made of stainless steel, aluminum or copper. It is usually installed 2 m above the highest point of the protected building. This type of lightning rods is the simplest to implement and quite cheap.
A cable lightning rod consists of two masts installed around the perimeter of the protected object, and tensioned steel cables between them. An lightning protection network is a mesh of metal rods laid on the roof of a building with a certain pitch.
For small private houses, an excellent lightning receiver can be metal roof. If the roof of the house is made of a different material, then it is better to choose a lightning protection mesh for the protection device, and for wooden country houses active protection is used more often.
Down conductors
Current flows to the grounding device through down conductors. In accordance with the above Instruction RD 34.21.122-87, down conductors in a residential building can be various designs buildings made of steel, aluminum or copper (frames, fire escapes, fittings reinforced concrete slabs). Special down conductors are usually laid outside along the perimeter of the building at intervals of 25 m. The effectiveness of down conductors depends on the continuity electrical network. They are usually connected to the lightning rod and grounding devices by welding.
Grounding
The lightning charge in the soil is dissipated using grounding devices. In accordance with Instruction RD 34.21.122-87, they are most often reinforced concrete foundations or vertical electrodes that go deep into the ground. The latter type of grounding is necessarily protected from corrosion (therefore, it is usually made of copper-plated or galvanized steel), and the electrodes are securely connected to the horizontal busbar and to each other using special connectors.
Making a lightning rod at the dacha with your own hands
So, if you have come to the conclusion that you want to make a lightning rod for country house with your own hands, then you need to know how this device is made. First you need to make a rod current collector, to which a current conductor will then be attached, which can be made from ordinary iron wire. Just choose a wire with as large a cross-section as possible, for example 6-8 mm. The conductor also connects the current collector to the ground loop.
The ground loop can be made from an iron strip measuring approximately 4x50 mm. The electrode should be made of steel rod, choosing a diameter of at least 18 mm. Please note that all connections should only be made using welding machine. If you do not have this option, you can use bolted steel clamps, but such connections will be less effective.
2) Fastener material handicraft When a lightning current passes through, with a high degree of probability it may not withstand the enormous temperatures and will simply melt. Therefore, it is always necessary to know the parameters of the materials used and carry out necessary calculations. But it’s easier to buy ready-made components from lightning protection manufacturers, especially since the prices for fastening elements, especially domestic ones, are acceptable. Plus, you will receive the necessary advice from specialists on proper installation.
3) There is a rule: you either make isolated lightning protection and maintain the required breakdown distance, or connect everything metal elements together and connect to ground. Here the author uses insulators and, accordingly, the first method, which means the air gap between the receiver/down conductor must be no less minimum distance R, which in this particular embodiment should be equal to 300-400 mm, which is not noticeable. Without grounding the roof, a dangerous potential difference is guaranteed to arise here.
4) The option of a ground electrode in the form of a single pin stuck into the ground cannot be considered reliable no matter the soil resistance, especially since the down conductor through which the discharge from the lightning rod arrives is also the only one. Even in the days of the USSR, with a complete lack of knowledge and calculated parameters of soil resistance, focal grounding was always done in the shape of a triangle or a U-shaped circuit.
Basic typical diagrams of country lightning rods
Once again, in more detail, let’s talk about three known types protection devices installed on the roof of buildings.
The type of lightning rod chosen for a country lightning rod determines the type and scheme of its protection. TO standard schemes include the organization:
- lightning protection mesh;
- rod lightning rods;
- cable lightning rods.
For flat and gable roofs For cottages, regardless of the roofing material, experts recommend using lightning protection mesh. To organize it, steel, copper or aluminum rods with a diameter of up to 8 mm are used. The mesh is installed directly on the roof or under the insulation if the roof base is not flammable (Instruction RD 34.21.122-87).
Depending on the level of protection, down conductors are mounted directly to the mesh along the entire perimeter in increments of 10 to 25 cm.
A lightning protection rod circuit is a metal pin attached to a chimney or other roof structure at least 2 m above its highest point.
The installation of the rod is carried out correctly if the protected object completely falls into the base of the cone with the apex at the extreme point of the lightning rod. Increasing the height of the rod expands the protected area. This type of lightning rod is suitable for both private and industrial facilities with complex roofs.
For gable roofs For low buildings, you can also use a cable circuit for a country lightning rod. To do this, between the supports installed on the skates, stretch steel rope. Its ends are usually adjacent to one down conductor, which transmits current to grounding in the ground, which looks similar in appearance to " chicken foot"If the dacha lightning rod circuit is executed correctly, lightning discharges go into the soil outside the protected house. When installing lightning protection of this type It is important to take into account the sag of the cable.
The choice of a scheme for organizing a dacha lightning rod is influenced by many factors, parameters and conditions. Therefore, this is a rather complex and responsible event that requires certain professional knowledge and experience. Our company will help you design and install the most effective lightning protection for your home. In addition, we provide turnkey lightning rod installation services. The section "Our objects" contains photos of lightning rods and a description of our completed projects.
How and where to buy a lightning rod
A lightning rod that protects against a direct lightning strike will work like a clock if you choose it wisely and correctly necessary materials to create effective and reliable lightning protection for a building. The price of a country lightning rod is influenced by the following parameters:
- level of protection;
- lightning rod diagram;
- technical difficulties of project implementation;
- type of materials used and scope of work.
Today, numerous online stores offer big choice rods and cables made of steel, copper and stainless steel, as well as holders and clamps and give wonderful description their goods. However, it is difficult to make a lightning rod of impeccable quality on your own. In addition, no one will guarantee the operation of a system assembled from materials with different performance characteristics.

We all know that lightning is beautiful only from a distance, but for a person its strike can be fatal. A lightning strike can also damage equipment or cause a fire. IN a private house Lightning does not strike very often, but if it does happen, it will be extremely difficult to cope with the consequences.
Today we will talk about lightning protection of a private house and how a lightning rod is designed.
Features of lightning protection of a private house
When thunderclouds are approaching in the sky and lightning is piercing it, a considerate and intelligent person will not be afraid of them, because he protected his home from their direct hit.
So, a good owner will definitely show interest in how to provide lightning protection for a private home. You don’t have to worry if your private home is located next to a tower equipped with a lightning rod or power lines. But at risk of being struck by lightning are buildings that:
- have a single location;
- built on a hill;
- are located next to a pond.
A lightning rod should be planned at the stage of construction of a private house. Yes, it should make a lightning protection circuit during construction. Private houses belong to the third class fire safety, accordingly, they must be installed on them with a lightning rod without fail.
The choice of the right type of lightning protection for a private home depends on a number of factors:
- Original condition of the house.
- Location conditions.
- Climatic conditions of the area.
- Soil type.
Necessarily take into account the location conditions your house. So, if lightning strikes a tree, an antenna, or a pole near a house, they can create a screen effect and the building will also fall into the affected area.
remember, that different types soils differ in their conductivity and resistance, which should be taken into account when choosing the section of the strip and the size of the contour depth.
If the climate of the area is such that the number of thunderstorm periods per year exceeds 40 times the mark, and the house is located near water, then the risk of being struck by lightning increases several times.
How a lightning rod is designed for a private house
The principle of operation of a lightning rod is quite simple: the house is protected from lightning strikes due to the fact that the discharge is discharged to the ground.
However, the effectiveness of a lightning rod is possible only with the complex construction of a system that consists of two protective systems: external and internal.
Internal protection must protect equipment from power surges during a thunderstorm. And even if the discharge strikes within a radius of several kilometers, a surge suppressor is still needed.
If you do not have such protection, then when a thunderstorm front approaches within three kilometers, turn off all electrical appliances.
A external system protection is needed to ensure the safety of the house and its inhabitants during a thunderstorm. A simple lightning rod consists of the following elements:
- Lightning rod.
- Supports.
- Down conductor.
The lightning rod is metal conductor up to one and a half meters in length, which takes on a lightning strike. Install such lightning protection in country house follows at its highest point:
- roof;
- chimney;
- TV antenna
This lightning protection is suitable for installation on a metal roof, and if the roof is slate, then you need pull the metal cable on wooden supports up to 2 meters long and cover it with insulators.
On tile roofs, you need to stretch a special lightning protection mesh with down conductors along the ridge. Down conductors are needed to connect the lightning rod to the ground loop. They represent steel wire, which should be laid along the wall of the house and welded to the lightning rod and ground loop.
Lightning protection grounding includes two connected electrodes, which driven into the ground. According to the rules of grounding household appliances and lightning protection should be common. The radius of a lightning rod depends on its height.
If the lightning rod is made correctly and with high quality, then it will represent the least resistance along which the lightning discharge will be redirected from the house to the ground.
How to make lightning protection for a private house with your own hands
So, we figured out how lightning protection for a home works, and how to choose it depending on the type of roof. Now we will talk about how to make high-quality lightning protection for your home with your own hands.
Will serve as a lightning protection mesh metal wire structure with a diameter of six meters, which is made by welding. It should be laid on the roof and connected to the ground loop with several down conductors.
This mesh is suitable for non-metallic roofs to protect one building, since other buildings are located at a lower level. The mesh can also be laid on the roof during the construction of the house.
The protective wire can be made as follows:
- Stretch the cable on insulators between two metal or wood supports.
- Installation is carried out at a height of 0.25 m on the ridge.
- The wire diameter must be at least 6 mm.
You need to make a loop around the wire pipe and attach it to the lightning rod using soldering or welding. The current conductor is also made from the same wire. As a result, we get a hut-like protective zone, which is suitable for roofs made of any material except metal.
Pin lightning rod- this is a pin with the following parameters:
- the cross-sectional shape can be round, rectangular or square;
- pin length is at least 0.25 m;
- cross-sectional area 100 square mm.
It is the pin that takes the key lightning strike, so it must be able to withstand maximum loads dynamic and temperature nature.
The material for the pin is selected so that it is not afraid of oxidation, this can be galvanized steel or copper, therefore it is impossible to paint such a lightning rod. The cross-sectional diameter of the rod or pipe must be at least 12 mm. You need to weld the end of the hollow pipe. The structure should be installed on the roof ridge on a mast of the required length.
The down conductor directs electrical discharge into the ground. It must be attached to the overall structure by soldering, welding or bolting. The contact area must be at least twice the cross-sectional area of the parts that are connected to each other.
Such protection is suitable for metal roofs, but remember that the roof itself must also be grounded.
Grounding for lightning rod
A grounding electrode is needed to drain lightning current into the ground; it has a small share electrical resistance. Grounding should be laid away from the porch of the house and the paths next to it, preferably at a distance of about five meters.
If the soil is wet and groundwater lie less than one and a half meters, then you need to use horizontal ground electrode. You can make it yourself as follows:
- Along the house, dig a ditch the width of a shovel, about six meters long and about a meter deep.
- Drive three galvanized water pipes with a diameter of 20 m and a length of 2 m into the bottom of the ditch every three meters. Leave about 5 cm on the surface.
- Take a wire with a diameter of at least 8 mm and weld it to the pipes. A down conductor still needs to be welded to the middle pipe. You can also weld bolts to the pipes to connect them with copper cable.
- Lubricate the bolts with grease and bury the pipes.
If the soil is dry and the groundwater is deep enough, then do vertical ground electrode:
- take two rods 2–3 m long;
- drive them into the ground to a depth of about half a meter and at a distance three meters from each other;
- connect them with a jumper with a cross-section of 100 square meters. m.
Such grounding can be used for the purpose protection of electrical devices and shields. Remember that during a thunderstorm it is extremely dangerous to be within a radius of four meters from the grounding, otherwise there is a risk of being exposed to step voltage.
Lightning protection can also be installed on a tree if it is more than twice as tall as the house together with the antenna and is located at a distance of 3–10 meters from the house. In this case, lightning protection is made of wire with a diameter of about 5 mm, with a one-way descent and one grounding in the form of a loop.
If you have installed lightning protection against linear lightning, it will be ineffective when struck by ball lightning. In such a case, so that ball lightning didn't get into the house close all windows tightly, doors, chimneys, and check that the ventilation units are equipped with copper or steel mesh wire with cells of about 3 cm and reliable grounding.
When installing and maintaining lightning protection, remember the following tips and recommendations:
Remember, in order for lightning protection of your private country house could serve you well long years and protect it in cloudy thundery weather, need to be installed correctly and take care of it regularly.
People living in private houses are afraid of lightning striking their homes. Some of them, in order to protect themselves from this, are thinking about protecting the building. Their concern is understandable, since there are regions where lightning intensity can reach up to 80 hours a year. In such areas it is necessary to install lightning rods. The construction of such a structure naturally requires certain costs. However, in some cases they can be minimized if you do all the work on creating a lightning rod yourself.
Protection zone
Currently, structures that protect against lightning are distinguished based on the degree of reliability. There are two types:
- type A;
- type B.
Lightning rods of the first type provide 99% protection, which allows them to be called the most reliable designs against lightning. Structures of the second type provide 95% protection.
Device
If you are seriously afraid of lightning getting into your home and, in order to protect yourself from this, you have decided to install a lightning rod, then in this case, during work you will need to create the following elements of this building:
- lightning rod;
- down conductor;
- ground electrode.
Lightning rod
This is a device that looks like a metal rod. After installation, it will rise above the roof of the building. This is where lightning strikes will fall. Thus, it is ensured reliable protection buildings. In addition, such a device is able to withstand severe voltage loads that occur when struck by lightning. When creating this element, you can use various materials.
The best choice - strip or round steel, whose cross-sectional area is at least 60 square meters. m. This element is subject to certain requirements in terms of length. This parameter must be at least 20 cm. The device must be placed strictly in a vertical position. The most high building on the site is an ideal place to secure it.
Down conductor
The current conductor has the form of a thick wire with a diameter of 6 millimeters. To create it the best choice- Cink Steel. Regarding its location, it is better to choose areas where lightning is most likely to strike. For example, good place the edge of the pediment can be used to accommodate it. It can also be placed on the ridge. This lightning rod element is secured close to a private house, but with a slight offset of 20 cm.
If the house has a roof made of materials that are easily flammable, then in this case a gap is all the more necessary. To secure the down conductor special fasteners must be used: nails and staples. For greater reliability of fastening this element, you can use clamps.
Ground electrode
It is necessary to divert a current strike from lightning to the ground. When choosing a material to create this lightning rod element, it is necessary to use one that conducts electrical charge well. It is also necessary that the material has minimal resistance. If we talk about its location, then this lightning rod element is placed not far from the porch of a private house, at least 5 m. It is not recommended to install the ground electrode in the immediate vicinity of paths, as well as in places where people may be. After placing it, you can create a fence around it to make sure it doesn't cause harm.
When installing a fence from the ground electrode, it is necessary to make an indent of 4 meters, and the fence itself should be arranged along a radius. If the weather is good outside, it will not do any harm. But if it’s cloudy, and especially if a thunderstorm has begun, then standing in close proximity to it can be dangerous to your health. The ground electrode is installed in the ground. The decision regarding the depth of this element is made by the owner of the house himself. The following points must be taken into account:
- soil type;
- availability of groundwater.
For example, if the site is dominated by dry soil and the groundwater level is low, a ground electrode consisting of two rods is installed. The length of each of them should not exceed 3 meters. Components of this element must be secured to the jumper, whose cross-sectional area should be 100 square meters. m.
When this is done, the grounding conductor is secured to the down conductor by welding. After this, it is immersed in the ground to a depth of 0.5 meters. In the event that the soil on the site is peaty and has high humidity, and groundwater is located close to the surface, then there is no possibility of grounding half a meter. Therefore in this case nessesary to use metal corners , which will act as a grounding conductor. They are immersed to a depth of 80 cm.
If under construction multi-storey building, then in this case, work on installing a lightning rod is carried out by specialists. These structures have their own protection zone radius, which makes it possible to place them on every building. Before installing this structure, it is checked whether the already installed lightning rods are capable of providing lightning protection to the constructed building or whether it is necessary to construct a new one.
In the case of individual houses, the issue with the lightning rod is decided by the owner himself. There are a number of factors in the placement of buildings that can minimize the risk of lightning striking a house:
- if a house is located in the lowest place on the site, the probability of lightning striking it during a thunderstorm is small;
- if there is a building next to the dwelling high altitude, then when lightning strikes it is more likely to be hit by lightning. This way your home will be safe;
- If a lightning rod is installed on a neighboring house, then its protective zone may extend to your house. And in this case there is no great need for a lightning rod.
Thus, it cannot be said that a house that does not have a lightning rod is at high risk of being struck by lightning.
Options for creating a lightning rod
If you have inspected your and neighboring houses and as a result discovered that nearby buildings do not have such protection as a lightning rod, then in this case the most reasonable thing is to do the work to create it yourself. Particularly dangerous are buildings whose roofs are covered with metal tiles or steel sheets. Although such a roof looks attractive, the lack of grounding increases the risk of lightning striking such a house.
In most cases, installation of this roofing is made on a lathing made of wood. This ensures charge accumulation. Discharge of such a device can only occur after a thunderstorm. A person touching it can receive a current discharge of several thousand volts. In addition, do not forget that a spark may occur after a lightning strike, from which a wooden house can easily ignite.
If you want to avoid such unpleasant situations, then you need to think about grounding, which should be located every 20 cm. If your home has a metal roof, then in this case you can refuse to create a lightning rod. The roofing material itself will be an excellent lightning rod.
To save your home from lightning strikes, you can install a lightning rod on its roof. However, other options are also possible. If there is a tall tree, then you can install a lightning rod on it with your own hands, but provided that it is located at a distance of three meters from the building, and its height is 2.5 times greater than that of your house.
If you find this lightning rod option attractive and decide to arrange it, then you will need 5 mm wire. First you need to prepare it, then one end needs to be buried in the ground, having previously welded it to the ground electrode. The other end will act as a lightning rod. It must be placed at the very top of the tree.
If there is no tall tree on your site, you can use an air-termination mast with two metal rods. Their installation is carried out at opposite ends of the roof. The drain in this case will act as a down conductor. Great importance has the material of its manufacture. It must be metal. In this case, you should also not forget about the device of the grounding electrode.
Conclusion
Regardless of which method you choose to install the lightning rod, you must remember that by properly installing this structure, you will ensure comfortable living in your wooden house. But it is necessary to periodically check the condition of the lightning rod created with your own hands. Special attention must be paid to its connections. There should be no violations in them. Only in this case you can not be afraid of lightning striking your house.
