Abstract

This paper presents a transient electromagnetic interference study in a right-of-way shared between an 88 kV transmission line and a 14'' pipeline, with a complex approximation layout based on real project data, and analyses of the induced voltages along the interfered pipeline due to lightning discharges. A circuit model implementation based on the Alternative Transients Program (ATP) with frequency-dependent parameters is built to predict the transient inductive interference effects and ground currents caused by lightning surges. The model is validated using industry-standard software, and then leveraged to perform a detailed investigation of how lightning discharges with different characteristics and how distinct soil properties affect the propagation of the induced voltage wavefronts along the interfered pipeline.

RESULTS are expressed in terms of electromagnetic interference (EMI) zones within which the pipeline may be subjected to potentially hazardous voltages.
