Abstract
A cathodic protection system utilizes dynamic control of an output from a power supply to vary an impressed current applied to a structure to be protected proportional to a measurement of stray electrical current. The current is also supplied to an anode bed in an amount sufficient to maintain the structure more negatively charged than the anode bed such that the stray electrical currents are directed away from the structure, thus avoiding electrolytic attack.
