Temperature rise in underground impressed current anodes

Journal Article · · Corrosion (Houston); (United States)

Smith and Denisons analysis of current and power relations in underground impressed-current cathodic-protection systems supports the conclusion that anode failure may result from high anode operating temperatures. The power lost through anode-to-earth resistance is transformed to heat around the anode. Formulas derived for estimating anode temperature in soils of varying resistivity and thermal conductivity can aid corrosion engineers in designing a cathodic-protection circuit that will not overheat the anodes.
