New underground corrosion problems have been experienced by electric utility organizations following widespread installation of direct-buried cables for power distribution at 7.2/12.47 and 14.4/24.9 kV. The new corrosion phenomena are not well understood. To obtain data, specimens of cables and cable material were buried in 1976, at several random test locations. Observations were made of cathodic currents of individual specimens connected to the multigrounded neutral of an electric system, and also of dc potentials of isolated specimens. Results based on the first eight months of observations were reported at Corrosion/77 and have been published in Materials Performance.1
