Abstract
The corrosion control experiences of the author with underground rural distribution (URD) systems are presented. The discussion includes (1) survey testing procedures, (2) designing of cathodic protection (CP) systems, (3) criteria for selecting material, (4) installation and maintenance procedures of CP systems, and (5) an economical evaluation of CP system installations. It is the opinion of the author that impressed current systems, supplemented by galvanic sacrificial anodes, can provide economical corrosion protection for existing direct-buried copper concentric neutral wires
