TerraDyne®
Electrolytic Grounding Systems (EGS)
TerraDyne® Electrolytic
Grounding System is a multipurpose grounding system. It has been designed
to provide long term protection from lightning, electrical transients,
static discharges, electro-magnetic interference and other electrical
hazards. The system may be used for virtually any application where the
protection of machinery, electronics, and personnel is important.
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.
Principles of Operation
How Electrolytic Grounding Systems Operate
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 ports that have been positioned in the electrode. This
process improves the soil conductivity and dramatically reduces
electrical resistance between the electrode and the earth.
TerraDyne® also takes advantage of another benefit. The hole bored 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 includes TerraFill® as the backfill material.
