Title: Method for reducing electrolytic interference with metal structures

Abstract: A parallel galvano-electrolytic current path is provided to conduct a current comprising (i) a portion of the interfering current and (ii) currents arising due to varying degrees of polarization of metal surfaces. The current is measured and a variable resistor inserted in the galvanic path is reduced in value until zero current flows through the parallel galvano-electrolytic current path in the direction of the electrolytic portion of said galvano-electrolytic path. Also disclosed is a circuit for applying said method.
