Abstract

This paper deals with the influence of steel non-linearity when calculating the induced current/voltage on a pipeline circuit with earth return under 50-60 Hz induction by power lines or electrified railway lines. By having at disposal the measured curves of the per unit length pipe internal impedance versus the current flowing in it, one can calculate induced voltage and current on the pipeline-earth circuit by means of the successive approximations method. The paper presents some comparison of the results when ignoring or not the steel pipe non-linearity. In certain cases, the differences can be significant.
