Computerized Analysis of Power Systems and Pipelines Proximity Effects

This paper describes the computerized analysis which was conducted to ensure personnel safety and pipeline integrity during power system faults occuring near the Trans Quebec & Maritimes gas pipeline. The pipeline section considered was constructed in the vicinity of two Hydro-Quebec power substations and a number of high voltage transmission line structures. The effects of electromagnetic induction and through-earth conduction caused by currents originating from Hydro-Quebec facilities during ground fault conditions are examined and their impact on the gas pipeline are quantified.
