Foreword:
Deep earthing concept is a system without extra connection points. The types of earthing electrodes are copper and galvanized steel wires which is pulled down by means of 0.85 m steel tubes ("rods"). A hardened steel tip locks the electrode into the leading rod. For each extension rod the wire is pulled a further 0.85 m down alongside the rods. Earthing resistance may be continuously monitored at the other end of the wire, the driving down is interrupted when a satisfactory low resistance is reached. The top extension rod is pulled up and reused
