CP Criteria Assessment in the Presence of AC Interference

Marco Ormellese, Luciano Lazzari, Sara Goidanich, and Valentina Sesia, Politecnico di Milano

On the basis of laboratory test results, cathodic protection criteria in the presence of an AC interference are discussed: AC density threshold and true potential limit are evaluated. Test were perfomrened in soil simulated conditions. Cathodic protection was in the range 0.2 - 10 A/m2; overlapped AC density was in the range of 1 to 500 A/m2.
