Earth current criteria may be defined as being based on the theory that complete and adequate cathodic protection is achieved when all points on the surface of a buried structure are receiving current through the surrounding earth, cancelling and preventing the discharge of anodic currents to the earth and thereby controlling corrosion. The study and measurement of earth currents is a major consideration in the cathodic protection of underground structures.
