• Resumen

  • Purpose – The purpose of this paper is to make a study of electromagnetic interference between electrical power lines and nearby underground metallic pipelines.

    Design/methodology/approach – The equivalent electrical circuit of the studied electromagnetic interference problem between electrical power lines and nearby metallic pipelines is created and solved using a loop currents technique based on a hybrid method. The used circuit solving technique was implemented in a software application developed by the authors.

    Findings – The authors have identified the influence of phase sequence on induced voltage level in an underground pipeline for a double circuit electrical power line. Also the effect of different normal operation and phase to earth fault currents have been revealed.

    Practical implications – The study has been made through a research project with the Romanian gas transportation company, in order to find the proper protection techniques for underground metallic pipelines.

    Originality/value – The paper reveals the influence of some electrical and geometrical parameters that have not been studied in detail previously.
