Prediction Method for Buried Pipeline Voltages Due to 60 Hz AC Inductive Coupling Part I-Analysis

Abstract
The voltages induced on gas transmission pipelines by 60 Hz ac power transmission lines sharing a joint right-of-way are predicted using electrical transmission line theory. Thevenin equivalent circuits for pipeline sections are developed which allow the decomposition of complex pipeline-power line geometries. Programmable hand calculator techniques are used to determine inducing fields, pipeline characteristics, and Thevenin circuits.
