Safety, electromagnetic interference, coating stress voltage, and induced potential


This paper studies the electromagnetic interference problems arising in corridors shared by transmission lines, pipelines, and railways, etc. A new circuit model method for analyzing interference problems is introduced. This method can be used to compute the combined inductive, capacitive, and conductive interference level efficiently and accurately. Practical examples are examined and results obtained using the new method are presented and compared with those obtained using the conventional circuit model method and the exact electromagnetic field method. It is shown that the new circuit model can be applied to problems which cannot be solved using the conventional circuit model.
