A well-designed Earthing system is essential for any electrical installation to avoid dangers associated with fault currents. Good Earthing protects both equipment and people against dangerous step & touch voltage. A low resistance Earth Termination System aims:
To provide security for people by limiting the step & touch voltage.
To protect installations and equipment by providing a low impedance path for fault currents.
To improve the quality of the signal by minimizing the electromagnetic noise.
To provide an equipotential reference voltage for the system.
