Abstract

A measuring system to determine the true peak potential, without ohmic drop error, is described. There is no alternating current (AC)-induced corrosion when the true max, peak potential is below the potential for cathodic protection (CP). Methods are studied to determine the importance of AC corrosion when the potential is higher than the critical potential for CP during a part of the AC period.
