Course overview
In this 1-hour self-paced course, participants will gain a comprehensive understanding of the three primary coupling mechanisms - Electrostatic (Capacitive), Resistive (Conductive), and Electromagnetic (Inductive) - that can result in electrical interference for pipelines sharing a right-of-way with power lines. Learners will explore the intricacies of these mechanisms, their potential impact on pipeline infrastructure, and the strategies for mitigation. By the end of the course, participants will be equipped with valuable insights to effectively address and prevent interference issues, ensuring the safe and reliable operation of pipelines in proximity to power lines.
