Abstract
A power supply for the cathodic protection of metal objects in a conducting medium compares reference and measured potentials with a pre-determined potential in the regulating circuit. Combined with an alarm circuit, the boundaries set for the supplied voltage and the protection current form a unique fully automatic system.
