When the cathodic protection current stops flowing from the anode to the structure being cathodically protected, the polarized structure will begin to depolarize. In most locations, an unprotected buried steel tank will corrode. The first criteria is 100mV of polarization – this is a pretty simple criteria to apply in that you measure the potential of the structure without any CP being applied (native potential) and then after applying cathodic protection for a sufficient period of time for polarization, measure the potential again and if the potential difference is greater than 100 mV – this is commonly known as the 100 mV shift criteria. The anodes are located sufficiently far enough from the surface to be able to consider them electrically remote from the structure and thus able to project current into a congested underground environment or distribute current for miles in each direction for isolated pipelines. How Cathodic Protection Works . This shift is in potential is called polarization. When connected in a circuit, cathodic protection current flows from the anode (more negative) to the structure (less negative). Find materials, components, equipment, MRO supplies and more.
