Abstract
In this case study we integrated 3D modeling including polarization into the design of Direct Current (DC) stray current interference mitigation associated with Light Rail Transit (LRT) systems and adjacent metallic pipelines. Simulation results identify interference hot spots by predicting interference current density and potential shifts along pipelines under study. This approach in analyzing stray current interference provides proactive monitoring solutions to address pipeline integrity concerns. The simulation tool also predicts pipeline polarized off potentials, which could be measured at recommended test post locations and compared against NACE potential shift criteria during future monitoring.
