Abstract
The conventional potential measurements and evaluation methods of cathodic protection diagnostics do not give reliable results in some practically important cases: in systems where the whole amount of cathodic protection current cannot be interrupted for any reason or the equalizing currents affect the protection to a significant level or interference with other cathodic protection systems is encountered. The paper discusses a model and its practical application dealing with these difficult cases. The test measurement evaluation results justify the theoretical model. On the basis of the theory a very simple measurement method is proposed for the determination of the coating defects IR-free potentials.
