Earthing -Grounding
Earthing system – in well design – is basic for any electrical installation to avoid being associated with fault currents, as established in the main earthing standards.

Earthing system with Low Voltage Earth Termination is aimed to:

1. Provide security for persons by limiting the touch voltage.

2. Protect installations and equipments by providing a low impedance path.

3. Improve the quality of the signal by minimizing the electromagnetic noise.

4. Fix a reference voltage for the system.
This Drawing Just Illustrate different types of our products used in earthing, it is not a real estate.

A Low earth resistance is essential for obtaining an efficient Earthing.
Conductors with an accurate section should be used in order to carry the expected current.
Besides, they must be durable against corrosion.

The value of the electrical resistance must be Measured, isolated from any other conductive element.
Therefore, it is necessary to use disconnectors in order to separate the earthing from the rest of the installation during the measurements.

Other determining factors for designing earth termination system are the following:
The resistance should be measured regularly so it is necessary to place an inspection pit.
The soil humidity will reduce the earthing resistance.
Earthing enhancing compounds reduce the soil resistivity.
Security distances for buried electricity and gas installations have to be respected.
Buried pipes and water tanks have to be bonded equipotentially with the earth system
