Multi-conductor transmission line with nonlinear impedances: Application to 50Hz studies
This paper presents an algorithm for the evaluation of currents and voltages along a multi-conductor transmission line having non-linear impedances due to the presence of ferromagnetic conductors; we assume that these impedances are function of the current carried by the relevant conductor...

| description | This paper presents an algorithm for the evaluation of currents and voltages
along a multi-conductor transmission line having non-linear impedances due
to the presence of ferromagnetic conductors; we assume that these impedances
are function of the current carried by the relevant conductor so that the
equivalent circuit modelling the line is non-linear and has to be solved by
means of an iterative procedure. The present paper can be considered as a
generalization of our previous works successfully applied to
single-conductor lines with earth return. Some examples of application to
typical 50-60 Hz interference studies between power/railway lines on
telecommunication cables and pipelines are shown. |
