How is Ligthning Formed?
The water molecules inside a cloud are
constantly colliding with each other, creating electrostatic
charges. Usually the positive
charges are located at the top
part of the cloud and the negative ones at the bottom. Statistical studies
realized around the world show that 95% of the clouds have negative charges at the bottom. When
there is an excess of charges, these look for a discharge path to
earth, generating the lightning.
Usually the clouds send
descending guides with negative charge and the earth sends ascending
guides with positive charge; when these guides touch each other,
they break the dielectric rigidity of the air and the lightning is
formed, which is accompanied by high temperatures, voltages and
Features of the Lightning Rod
The electromagnetic Lightning Rod System TERRAGAUSS
is designed to avoid
probability of a lightning falling down in a diameter of
160 meters, because it generates a
negative electric field, which, by the principle of repulsion of
equal charges, prevents that
lightning fall down within its protection area. For the
remaining 5% it
offers a safe dissipation path to ground, providing a less than two Ohms permanent resistance.

of the system are the
1. Itavoids the
lightningincidence by 95% and for the remaining 5%
offers a protection area of 160
meter in diameter at protection level 1.
2. Lower equipment and installation costs. Less installation time.
3. It protects from all the atmospheric discharges,
regardless the intensity or the amount of lightning within the
4. It guarantees a permanent resistance of less than 2 Ohms.
5. It works even in partially vandalized sites and
offers a multi-landed
system that allows draining the lightning even if the site is
vandalized, and maintains equipotential.
It does not
require any type of maintenance.
7. TERRAGAUSS offers a 10-year operation guarantee.
