CATHODIC PROTECTION SYSTEMS FOR STEEL IN SEA‐WATER: Calculation of Mat Sizes and Spread of Protection

Abstract

Relatively simple formulae are given herein for computing the spread of protection over large continuous areas according to the distance of the anode from the cathode. The distribution of the current is related to the potential gradient along the metal, shown to be directly proportional to the resistance of the sea path. Results accord with the experience that spread of protection is diminished rather than increased by emissive overprotection near the anode.
