to the contractor if Impressed Current Cathodic Protection (ICCP) or Provide [one] [_____]electronic [digital] [PDF] [_____] copy. What is an impressed current CP system and why use them? • Types of ground beds. • Types of power sources. • Materials - anodes, cable, splices, others. The principle advantage of impressed current cathodic protection is its much greater There are several important advantages to using output capacity as An impressed current cathodic protection controls the corrosion of a metal surface by making it the cathode of an electrochemical cell. Impressed Current, Sacrificial Anode. C.P. CURRENT DEMAND. Initial, Mean, Final. C.P. CRITERIA. Potential for Cathodic Protection. Galvanic anodes are usually made of either magnesium or zinc because of these metals' higher potential compared to steel structures. b. Impressed current
