In the method of cathodic protection with STOPCOR, we impose a current that comes from the sacrificial anode, negatively charging the installation we want to protect. In this way, while previously the installation was the anode of a galvanic cell (negative oxidative pole), it becomes the cathode of an electrolytic cell (negative reductive pole). This means that the installation remains negatively charged as it was before the application of protection, but the action is reversed and it tends to undergo reduction rather than oxidation.
