Abstract
A comparative analysis of domestic and foreign documents governing the design of cathodic protection systems has been carried out. The main parameters for evaluating the effectiveness were selected: “protective current density”, “protective current value” and “indicators characterizing the degree of protection against corrosion in the presence of cathodic protection”. As a result, the need for improving the domestic system for designing cathodic protection installations was established. First of all, attention should be paid to the decrease in protective current, protective current density and criteria for determining the need for cathodic protection.
