WebDec 25, 2024 · Introduction. Low frequency induction (LFI) in metal pipelines is a form of electromagnetic interference that occurs when high voltage transmission lines are run in parallel with metallic pipelines. The loaded phases on a transmission line and the pipeline act like single-turn windings on a large air-core transformer.
