Grounding

The part responsible for dissipating lightning energy

The ground connection is the part of the system that is responsible for safely dispersing the lightning current. For this reason, it is necessary to take into account some aspects at the time of its installation, since the safety of the entire installation will depend on the correct functioning of the ground connection.

First of all, for the system to function correctly, it is necessary that the value of the ground connection of the lightning rod with a priming device be below 10 ohms.

The layout of the grounding system is also important. The most suitable configuration to obtain the best value with the fewest number of elements is in triangle or goose foot.

In addition, whenever possible, it is convenient to have the earth connections interconnected and, preferably, by means of a spark gap.
