Experimental Evaluation of the Corrosion Performance of Copper-Bonded and Galvanized Grounding Electrodes

A variety of different electrodes is used for providing effective and safe electrical grounding. The ability of these electrodes to resist corrosion determines their useful service life. Copper-bonded steel and galvanized steel electrodes have been used for decades yet there is still much debate regarding the relative corrosion performance of each type of coating for applications in varying soil types and conditions. This article presents the experimental method and results from a series of laboratory corrosion tests that were carried out under controlled conditions on a range of electrode samples with both coating types in order to simulate their corrosion in soil according to an international standard.
