Abstract

The cathodic protection is used to prevent the oc-currence of accidental damages, leaks, generated by the corrosion of metallic structure of tubular material of trans-porting pipelines. Following the proper functioning of the cathodic protection system is made by monitorize of the main parameters: electrical potential pipeline-ground, in-jection parameters (continuous voltage, continuous cur-rent), respectively by measurement of insulating resistance of pipeline. In the case of monitoring of parameters by SCADA, it is constate the fact that are reduce the acciden-tal gases leakeges, generated by corrosion avoid the impact which is produced by the evacuation of hydrocarbons on the envirnment.

In this paper is presented an analysis method regarding the functioning of the cathodic protection, the DCVG method coloborated with a fuzzy analysis method, trough which are simultanely operated either the numerical dates, and lexical arguments, prior to locate, in the field, more precisely of the damage.
