Abstract

An analytical electrical transmission line model for an isolated buried pipeline is developed. Elements of the transmission-line model are derived mathematically using both field and circuit theory methods. Propagation along the coated pipeline in multilayer earth is studied analytically and modeled with a computer. The performance of the transmission line is analyzed. It is shown that time-domain reflectometry may provide the pipeline operator with an electrical method for monitoring pipeline-coating integrity
