Abstract :
Inductive and conductive coupling from a railway system containing booster transformers to a parallel telephone cable is studied. An electromagnetic field approach and a circuit theory approach combined with a grounding analysis have been used for the study. The two methods give results that are in good agreement with each other for currents and potentials in both the disturbing and the disturbed circuits
