The air terminals are dedicated to protect a building from direct impacts by moving the atmospherical discharges until the ground. The principle consists in creating one or several preferential impacts points of Lightning, with low impedance conductive elements, and then, to spread and dissipate the lightning current in the ground.
As a complement, the Surge Protector Device ensures the internal protection of the building, for the overvoltages with high amplitude damaging or destroying the installations, the electronic and electric devices. It will enable to limit the voltage by deviating it until the earth of the building.
