This paper describes the methodology used to identify and prioritize mitigation efforts of potential HVAC transmission line interference locations on a large transmission system in the United States. Satellite imagery with pipeline and HVAC transmission line GPS coordinates overlaid was first used to develop a data base of potential locations. The data base included the geophysical relationship of the location (pipeline/HVAC line geometry) pipeline coating type HVAC line voltage and tower/circuit geometry and site soil resistivity estimate. An algorithm was then developed using this data base to calculate and rank relative interference risk for each identified location. The algorithm included three primary risk factors; Steady state induced and fault personnel safety induced AC assisted corrosion and fault arcing pipe wall/coating damage.

Keywords; HVAC interference, pipelines, AC influenced corrosion, personnel safety, fault damage
