Lightning protection of buildings and structures

You can not even explain why it is worth spending on the purchase of a lightning protection system for the house: its absence is fraught with irreversible and irreparable losses resulting from discharges in the atmosphere. And even if you are in an area where thunderstorms occur extremely rarely, it is advisable. This will protect against possible fires, reduce the electromagnetic effect of current on the equipment in the house.

Lightning protection of houses can be external and internal, and for maximum effect it is best to combine them. Internal protection is to install a device that protects against the occurrence of impulse overvoltages in the presence of an effective grounding system. That it protects electrical appliances in the house, which may suffer during a thunderstorm. External lightning protection of houses consists of three devices: a lightning conductor providing lightning interception, and then diverting the resulting discharge to the ground (it has all the impact force, therefore its size must correspond to the size of the house); the current lead through which this discharge enters; grounding.
Best of all, if the installation of lightning protection will expert, pre-studied the terrain plan, the presence of buildings near the house, power lines and other things. The choice of protection system also depends on the material of the roof, the presence of metal objects on the building (pipes, hoods, antennas). If the roof is metal, then an air receiver is most often installed in the form of a metal rod, if it is wooden or slate - a metal cable is used that runs along the entire length of the roof (along the ridge).

The highest roof spot is most suitable for installing a lightning protection system. Moreover, a necessary condition is the connection of the interception rod with all metal objects that are located on the roof. Current leads are conducted on the outer walls of the house, keeping a distance of 25 meters from each other, and the farther from the windows and doors, the better. With the type of earthing determined after examining the type of soil and groundwater level. If the soil is dry and the groundwater level is low enough, then the vertical type is applied, otherwise it is horizontal.It is located away from the tracks and other places where people walk.
During the operation of the lightning protection system, damage is possible, therefore it is necessary to inspect it regularly for timely troubleshooting.
