SIMPLE FUNCTION

The earthing wire is inserted into and held by the steel tip. The extension rods have guiding pins to enter into the previous tube end to form a stable extension of the system. By monitoring the earthing resistance, the driving down may be interrupted at best point.

EARTHING

An earth electrode is a conductor placed in the soil with the purpose to discharge electrical current from a connected facility. The use of electricity with bad earthing includes a high risk. All suppliers of power must have approved earth electrodes at their facilities. It means that flash-over voltages, which can appear for different reasons are led into the soil so they do not cause any damages and/ or injuries. Earthing serves as, among other things, person protection, property protections, Electro Magnetic Pulses protection, lightning protection and similar.

PRINCIPAL DESIGN

The Elpress Deep Earthing concept is a system without extra connection points. The earthing electrode is a copper wire which is pulled down by means of 0.8 m steel tubes (“rods”). A hardened steel tip locks the Cu wire into the leading rod. For each extension rod the wire is pulled a further 0.8 m down alongside the rods. As the 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 re used. The driving down is normally made by Elpress Power Hammer for Deep Earthing with a suitable driving stud or with a sledge hammer and the driving cap FS61 or FS62C.
