Concrete encapsulated electrodes

Concrete encapsulated electrodes have been in use for over 40 years, and in general have been found to be an effective and safe component in grounding systems of industrial and commercial power systems as well as in lightning protection systems. As a current conducting medium, concrete is a fair conductor, similar to many moist soils. Concrete´s ability to quickly absorb moisture and release it slowly over a long period of time makes the electrode implementation practical, especially for dry locations. The alkalinity properties of concrete and the release of moisture and salts enhance the conductivity of the surrounding soil.
