Selection of the Grounding System
the adequate TERRAGAUSS
grounding system for grounding equipments, the full charge current of each of the equipment must
in amperes of the different equipment to be grounded, determines
the require capacity of the TERRAGAUSS grounding system. If there is a transformer or a UPS, as these two feed the
total electrical system, their capacity is the one to be
considered in the calculation of the full charge
Example: To select
the model of grounding system TERRAGAUSS to ground a transformer with
150 kVA, three-phase, with and
output voltage of 220
V, the full charge current of the transformer is
calculated by applying the formula
For this charge of 394 A,
the adequate model is the TERRA-400
(see product catalog), which is
capable of supporting a capacity of 400 A.
Selection of the Lightning Rod System
To select the lightning rod system
model and the quantity of systems to be installed, the type of installation to
protect and the perimeter to be protected (large and wide) must be
taken into account. One lightning rod system covers an
area of 160 meters
If the installation is a
Telecommunication Site, the required model is the
TERRA-PR1, for any other type of
installation, the model to use will be the TERRA-PR2.
