WebOver Protection from Cathodic Protection Systems. Getting the potential correct with the application of both Impressed Current (ICCP) & Sacrificial anodes to coated Items is essential. Under protection leads to corrosion & metal loss whereas overprotection can lead to coating delamination or blistering due to cathodic disbonding. WebMay 22, 2015 · 12. IMPRESSED CURRENT CATHODIC PROTECTION For larger structures, galvanic anodes can’t economically deliver enough current to provide complete protection. In this method, an impressed current is applied in opposite direction to nullify the corrosion current and convert the corroding metal from anode to cathode. ICCP systems use …

WebICCP systems are controlled to assure optimum protection. This control is obtained by inserting a third electrode between the anode and the cathode. The third cell/electrode is insulated and does not receive any anode current. This cell/electrode is freely corroding and it becomes the starting point — or reference — in eliminating corrosion.
