The TerraDyne® Electrolytic Grounding System (TEGS) is a multipurpose grounding system which may be used for virtually any application where the protection of machinery, electronics and personnel is important.

It has been designed to provide long term protection from lightning, electrical transients, static discharges, electro-magnetic interference and other electrical hazards. TerraDyne® EGS was designed for use in any type of soil condition. Some of the many applications where it is commonly used include cellular, radio and television broadcasting sites, computer facilities, power substations, communication centers, medical facilities and industrial plants.

TerraDyne® EGS is guaranteed for 30 years, with an expected life of at least 50 years. The systems are available in vertical or horizontal models. Vertical electrodes are usually installed using an augur or other drilling equipment. Horizontal electrodes are installed in trenches and utilized where the soil is rocky or excavation conditions are poor. The electrodes vary in length from 8 to 300 feet. Custom lengths, accessories and design options are available.

Protecting your expensive equipment is essential. TerraDyne® Electrolytic Grounding System enhances the performance of your electronics, stabilizes signal references and reduces the risk of injuries. The end result is a stable grounding system that provides undisturbed long-term performance while maintaining cost efficiency.

How it Works

The TerraDyne® EGS effectively utilizes a hygroscopic process to acquire moisture from the atmosphere. The moisture and the nontoxic chemicals inside the electrode react and create an electrolytic solution. This electrolytic solution leaches into the surrounding soil through carefully positioned ports. Soil conductivity is improved and dramatically reduces electrical resistance between electrode and earth. TerraDyne® also takes advantage of another benefit. The hole or trench for the installation is back-filled with TerraFill®, which also assists in substantially lowering the earth’s resistance by creating a direct, low resistance electrical connection between the electrode and the earth.

The use of TerraFill® will reduce impedance by increasing the effective contact area of the electrode to the soil. TerraFill® is an easily applied product manufactured from environmentally safe and stable products. Each kit includesTerraFill® as the backfill material.
