Cathodic Protection (CP) is a method of corrosion control that can be applied to buried and submerged metallic structures. In conjunction with coating, a properly designed and maintained CP will ensure a 100% efficient corrosion Protection System.
The Principle of CP is to prevent anodic sites occurring on the structure under protection by allowing anodic reactions to occur on specially designed and installed anodes.
The PR is designed to operate is constant current mode and the current is adjustable manually.
The PR has various protections like surge protection, fast acting semiconductor fuses, DC overload, DC over voltage, short circuit protection and AC under voltage and also fast acting current limiting which protects the PR from supplying current higher than the set value.
