TLDR
The results of field tests on a buried, 34-inch diameter gas pipeline adjacent to a 525 kV ac power transmission line for 54 miles are discussed in this article, where an excellent agreement of the predicted and measured results is shown for the location and magnitude of all induced voltage peaks on the pipeline.Abstract:
The results of field tests on a buried, 34-inch diameter gas pipeline adjacent to a 525 kV ac power transmission line for 54 miles are discussed. Comparison is made between measured inductive coupling data and predictions obtained using the theory developed in part I of this paper. An excellent agreement of the predicted and measured results is shown for the location and magnitude of all induced voltage peaks on the pipeline.read more

Recent advances in the mitigation of AC voltages occurring in pipelines located close to electric transmission lines
TL;DR: In this article, the authors present a new mitigation design approach which not only reduces AC voltages effectively and economically, but also provides cathodic protection for the protected pipeline, which is illustrated with results from computer simulations, which show how important it is to have an accurate electrical model of the soil structure in any interference study.

Analysis of Coupling Effects on Overhead VSC-HVDC Transmission Lines From AC Lines With Shared Right of Way
TL;DR: In this paper, the coupling of fundamental frequency voltages and currents on voltage-source converter (VSC)-HVDC overhead transmission lines from neighboring ac lines is analyzed, and the complementary modulation components at dc and second harmonic frequencies on the ac side of the converter resulting from the fundamental frequency coupling are analyzed.
