Back in 2018, we published a paper on a joint industrial R&D project, during which we performed detailed field measurements on selected pipeline segments in close vicinity to a High Voltage Direct Current (HVDC) transmission line during planned staged fault tests on the power line. Induced voltages on these pipelines were recorded during the HVDC staged fault process, which was conducted by the utility company. The measurement results from these tests were used for further validation or modification of an existing industrial guideline that focuses on the influence of HVDC power lines on metallic pipelines. Verification of future modeling results was another expected outcome of this study.

Stray Current Interference Simulation and Mitigation Associated with Light Rail Transit (LRT) Systems and Adjacent Metallic Pipelines – A Case Study

During operation of DC rail transit systems, DC current will follow the path of least resistance when returning to the Traction Power Substations (TPSS) to complete the electrical circuit. If the track-to-earth resistance (resistance between the train rails and surrounding soil) is not sufficient, current can leak off the LRT track system into the surrounding soil. Metallic facilities such as pipelines in the soil offer lower resistance paths for the current while returning to the TPSS.
