Investigation of electromagnetic interferences issues

Electromagnetic interferences between an existing high voltage power line and a gas stream network sharing the same right-of-way are evaluated. Induced voltages are determined for different steady state power line operating conditions, using professional software. To increase results accuracy, soil resistivity measurements were made along the distribution corridor and the appropriate equivalent soil model is identified. Obtained induced AC voltages values are compared to international regulation for potentially hazardous zones identification regarding pipeline corrosion.
