摘要：

In the present study we have made the numeric simulation by finite elements of the cathodic protection by printed current system for the buried duct. The built model was based on the steel carbon type SAE-AISI 1015, and this steel is the constituent material of the duct. This work allowed analyzing the potential distribution in the proposed project and the parameters that more influence the variation of this potential. Those parameters were such as resistivity of the soil, distance between cathode and anode, position of the anode, potential and diameter of the cathode. As a result it was verified that the resistivity of the electrolyte and the distance cathode/anode influence significantly the distribution of the potential of the projected system of cathodic protection.
