Impressed current cathodic protection systems are the ultimate state-of-the-art, long-term solution to corrosion problems, and are recognized as a superior alternative to sacrificial anode systems, which require frequent replacement. On the cathodic protection system coating: a liquid, liquefiable, or mastic composition that, after application to a surface, is converted into a solid protective, decorative, or functional adherent film. Cathodic protection monitoring system cpms the cpms cathodic protection monitoring system monitors above and below ground impressed current cathodic protection systems to ensure that proper cor-rosion protection is in place and operating at the right levels. Provided by a cathodic protection system the system requires electrical continuity of the structure and between the structure and test stations to determine structure-to-electrolyte potentials cathodic protection is a means of reducing corrosion of a metal by artificially. Testing cathodic-protection systems by marcel moreau t esting cathodically protected structures is rarely a “cookbook” type of procedure a clear understanding of cathodic-protection principles is a prerequisite for the correct execution of the monitoring procedure and a reasonable interpretation of the.
