Assessment of Inductive AC Interference Mitigation Strategies

Inductive alternating current (AC) interference on new and existing pipeline systems that cross, or are parallel with, overhead power lines is a serious concern. Two main issues are associated with this phenomenon: The electrical safety risk to pipeline personnel, sub-contractors working on a pipeline system, and the general public arises if any contact is made with a pipeline or its above ground appurtenances.The AC corrosion risk on buried pipelines, which is a phenomenon that has been identified with cathodically protected pipelines throughout the world.
