Impressed Current Cathodic Protection (ICCP)


 
 
The principle of ICCP is connecting both the anode and protected structure (cathode), to an external DC supply, providing an external (protection) electrical DC current from the anode to the protected structure. The protection current can be adjusted to the optimum level to achieve Cathodic Protection.

Impressed current anodes are having longer life than sacrificial anodes in cathodic protection due to their negligible consumption rate, durability and strength.
