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 a multi-layer earth is studied analytically and modeled with a computer. 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
