There are up to 100 flashes every second on the surface of the Earth.
The study of the phenomenon highlights 3 main families of risks arising from lightning strikes:
- Direct lightning strikes: The main characteristic of lightning is first of all the flow of a gigantic electric current which, by circulating in matter, causes significant damage to structures.
- Indirect lightning strikes: The power of the electrical currents involved causes induced phenomena and electromagnetic fields which cause the destruction of electrical and electronic equipment.
- Conduction phenomena: During a lightning strike to the ground, we see that the electrical charges dissipate in the ground and create a rise in electrical potentials. The difference in potential (voltage) between two given points in the ground or on the surface will allow current to flow.
Lightning presents many dangers and the consequences of a lightning strike are serious (spectacular damage, ignitions, destruction, explosions, deaths, etc.). To protect yourself, the implementation of a lightning protection system is essential.
The lightning protection system is composed of an outdoor lightning protection installation to protect against direct lightning strikes and an indoor lightning protection installation to protect against indirect lightning strikes.
We install a lightning rod to protect against direct lightning strikes.
A surge protector is installed to protect against indirect lightning strikes.
The lightning protection system is completed with equipotential connections to ensure total protection.
