“…Induced EMF can be calculated using Electric Circuit Methods (ECM) or Finite Element Methods (FEM) [9], [10], [11]. Using ECM the induced EMF per unit of length along the pipe, E_p (V/km), can be calculated using Equation (1) [12], [13].…”

“…The risk of corrosion is evaluated, and if it is Low, it is not necessary to calculate in any other place along the pipeline corridor. However, if the risk is medium or high, it is necessary to calculate the current density as a function of the position along the pipeline corridor using Equations ( 9) and (11).…”

A better use of space is achieved when different networks and systems, such as AC transmission lines, transportation systems, and pipelines share the same right-of-way. However, the electromagnetic coupling between the systems may cause the appearance of dangerous conditions for people due to exposure to high touch voltages, as well as for pipelines, caused by the activation of the AC corrosion phenomenon. These dangerous conditions require that during design the possible risks are assessed, and the corresponding mitigation actions are determined. This paper presents a simplified methodology for risk assessment using a practical approach and analytical expressions that can be easily implemented from information known while designing. Likewise, results are included for a case study that allow validating the proposed methodology and demonstrating the importance of this type of analysis.

“…Due to environmental and economic reasons, mainly related to construction costs and to their impact on local ecosystems high or medium voltage power lines are forced to coexist in a relatively narrow distribution corridor with gas, petrol or water pipelines with no access to new separate rights-of-way [1][2][3]. Figure 1, shows such a situation when an underground metallic pipeline is in the close proximity with an overhead power line.…”

This paper presents the distributed source analysis approach for treating the inductive coupling of power transmission lines with buried pipelines. The evaluation of the induced voltages in a pipeline which share the same path with a power line for a monophasic short circuit on the line is performed and also the analytical expression for current density induced in soil is calculated. The paper describes a practical case of subdivision of the zone of influence in sections (a circuit model) and a precise calculation of the induced voltages in different points based on the measured data, is performed in Mathcad, using special interpolation functions.

Combined effects of electrostatic and electromagnetic interferences of high voltage overhead power lines on aerial metallic pipeline

et al. 2022

The main purpose of this paper is to model and analyze the electrostatic and electromagnetic interferences between a HV overhead power line and an aerial metallic pipeline situated parallel at a close distance. The modelling of these interferences is typically done for safety reasons, to ensure that the induced voltage does not pose any risk to the operating and maintenance personnel and to the integrity of the pipeline. The adopted methodologies respectively for electrostatic and electromagnetic interferences are based on the charge and current simulation methods combined with the Teaching learning based optimization (TLBO) algorithm. The Friedman test analysis indicate that teaching learning based optimization (TLBO) algorithm can be used for parameters optimization, it showed better results. In the case where the induced currents and voltages values exceed the limit authorized values by the international CIGRE standard, mitigation measures become necessary. The simulation results obtained were compared with those provided respectively by the admittance matrix analysis and Carson's method, good agreement was obtained.
