Need: This project was a joint effort by the Pipeline Research Committee of the PRCI and EPRI to develop analytical techniques for determining the induced potential on pipelines that parallel electric transmission lines. This is an area of interest to both electrical system and pipeline operators. The purpose of this project was to develop analytical methods for the prediction and mitigation of voltages induced on natural gas pipelines by nearby AC transmission lines. Analyses of AC corrosion effects, personnel safety, and pipeline component reliability were performed.
Benefit: The study consisted of the following steps: - Consolidate known data concerning mutual effects arising from power lines and pipelines sharing a common right-of-way; - Develop a unified and systematic method for predicting electromagnetically induced voltages and currents on pipelines; and - Investigate mitigation techniques to minimize interference effects upon pipeline and component reliability and personnel safety. New techniques for interference prediction and mitigation were developed. Volume 1 details the engineering analysis and Volume 2 presents prediction and mitigation procedures.
Result: The contractor did develop the required analytical techniques, which are reasonable and supported by field test results. New mitigation methods were then developed and old ones evaluated for their effectiveness. All of the mathematical analyses were to be compared with several sets of data from field tests. The accounts of these tests are well documented in this report. The theoretical considerations are discussed in Volume 1 of this report. Included are discussions on prediction, mitigation, personnel safety and pipeline susceptibility. In Volume 2 techniques for performing the necessary calculations are presented without proof or discussion. It is anticipated that Volume 2 will be useful as a workbook.
