The very fabric of any protection systems is only as good as the earthing system that delivers the energy to ground. Earthing is a specialist field and requires experience and knowledge in all manner of conditions to achieve the ultimate protection system. Without due consideration, the entire network of equipment and it’s protection devices may be rendered useless as the energy strives to find the best potential earth.
Storm has developed many varied skills in achieving quality earthing systems at affordable prices. The primary function of an earthing network is to provide a solid and continuous connection to the general mass of earth. When designing a earthing network, the characteristics determining the effectiveness of an earth electrode or group of earthing components is the impedance which it provides between the earthing system and that general mass of earth.
Our experience in recognizing the influencing factors of earth impedance by recognizing the following generic principles such as: the resistance and surge impedance of the earth electrode system and the connecting conductors, the contact resistance between the earthing components and the surrounding earth mass, the resisitivity of the earth mass surrounding the earthing components, and the degree of earth ionization.
