Abstract

Summary form only given. This study describes a resistance reduction additive (RRA) for reducing and maintaining reduced resistance of ground electrodes over time. The RRA employed was a mixture of inorganic salts, some of which occur as residues from industrial mineral processing in Chile. Chemical characteristics of the mixture are described, as well as results of measurements of electrical resistance of ground electrodes over time with and without RRA treatment. Measures are also given for current intensities and loss of electrode mass in test electrodes buried below ground with RRA and within cell containers having a specific capacity. Small scale tests were made on the effects of impulse current in test cells containing electrodes treated with the RRA.
