Two steps numerical method for calculating the AC interference from a faulty power line on nearby buried pipelines

摘要

The paper presents a numerical method for evaluating induced voltages and currents, at power frequency, onna buried pipeline due to inductive and conductive coupling with a power line in fault condition; both thensystems can have generic layouts represented by broken lines. The algorithm consists of a two steps solutionnof a two wires transmission line model applied at first to the circuit shield wire(s) with earth return and thennto the circuit pipeline with earth return. This calculation method is particularly tailored for industrial and realncases applications. Copyright # 2010 John Wiley & Sons, Ltd.
