What Is Impressed Current Cathodic Protection? |
|
Answer» Simple impressed current cathodic protection system. A source of DC electric current is used to HELP drive the protective ELECTROCHEMICAL reaction. For LARGER structures, or where electrolyte resistivity is HIGH, galvanic anodes cannot economically deliver enough current to provide protection. Simple impressed current cathodic protection system.
