Cathodic Protection in An Urban Area With a Distributed Anode System^★

Discusses problems involved in applying cathodic protection to cables in an underground conduit system in an urban area where resistivity conditions are not uniform and where other subsurface structures are present. Distributed anode system was used in tests described. Impressed current was supplied by three small rectifiers. About 21 sheath miles of cable were protected of which 16 miles were bare lead sheath. 5.2.3
