Cathodic protection (CP) current distribution for long parallel pipelines in a common right-of-way, with a common negative junction box, have been ineffective as variables such us temperature, magnitude and direction of current flow, pipeline coating quality, pipeline diameter, and length of
pipelines, have resulted in problems to maintain adequate CP levels on the pipelines. To overcome some of these problems a Current Distribution System For Cathodic Protection (S.D.C) was designed and
tested in a major gas pipeline right-of-way in Venezuela. Field results are presented and discussed. Keyword: Current Distribution, Cathodic Protection, variable resistors.
