The Ionic Earthing Array is a complete solution suitable to any application requiring high performance earthing. Traditional methods such as drivenrods, tapes, plates or pipes give only partial and short term respite from the problem of good earthing. These passive conductors only enable an electrical fault to travel down to the earth, but does not affect how this electrical charge is dissipated into the soil. Therefore passive conductors in poor soil conditions will result in inadequate earthing protection.

Extensive experimentation and field trials have shown that high earthing resistance is the direct result of the absence of free ions to assist conductivity. The Ionic Earthing Array solves both the conductor and free ion problem simultaneously.

By utilizing advanced ceramic composites, metal alloys and natural chemical compositions, the IEA is able to provide a multifaceted proactive earthing protection strategy. The main body of the IEA electrode is manufactured from custom made copper alloy tubes to ensure maximum conductivity and prolonged service life. The IEA contains an ion rich crystalline mixture that when triggered by inherent air moisture will start the release of free ions into the soil. This continuously feeding of moisture and free ions to the surrounding soil will ensure the soil remains at a highly conductive state thus achieving a reliable low resistance to earth.

Another often overlook aspect of proper earthing is the effect of normal soil movement. Weather conditions and surrounding environmental fluctuations contribute to the expansion and contraction of soil. During periods of dry weather, the soil will often become loose and nonconductive. At such times traditional earthing arrangements will not provide reliable protection. The IEA has been designed with a special soil to electrode interface that expands and contracts accordingly. This enables the electrode to maintain constant contact with the surrounding soil and ensure a proper moisture level regardless of fluctuations in weather or environmental conditions.

By design the IEA electrode will increase the effective conductive soil mass through ion dispersion. As time progresses this conductive soil mass will grow larger. By installing the IEA electrodes as prescribed in the installation guide, all the enclosed soil will be conditioned to become a single highly effective conductive soil mass. This large mass of low resistance soil will be the best "foundation" upon which all electrical and electronic equipment on site can be referenced to.
