This paper deals with the design of cathodic protection for complex buried conductor networks, whereas the use of classical methods like the "attenuation equations method" for calculation of the cathodic protection potentials distribution might be a problem.

Abstract

This paper deals with the design of cathodic protection for complex buried conductor networks, whereas the use of classical methods like the "attenuation equations method" for calculation of the cathodic protection potentials distribution might be a problem. A suitable approach is based on a discrete net model that allows facing the problem through the traditional equations of linear electrical networks. This method, successfully tested in several situations, was initially proposed using a conductance-based net model. The present paper improves on this method, using simple numerical examples to demonstrate that the dual net representation through a resistance-based model allows an easier and more systematic solution of typical cathodic protection problems, offering to the designer direct insight into how control variables (such as placement and loading of protection feeders) affect the objective function (voltage profile or total current injection).
