Ac Interference from a Faulty Power Line on Nearby Buried Pipelines: Influence of the Surface Layer Soil (original) (raw)

IET Science, Measurement & Technology

The study generalises the calculation method described by Lucca, devoted to the evaluation of induced voltage and current on a pipeline due to a nearby overhead power line in a fault condition, from the case of homogeneous soil to the case of a two-layer soil. By means of some examples of calculation, it is put in evidence that the homogeneous soil hypothesis can lead, in some cases, to excessively precautionary results and, in other cases, to underestimated results. Therefore, a calculation method based on the two-layer soil model seems a better approach.
