Abstract

Installing pipelines in energy utility corridors containing high-voltage AC transmission lines subjects the pipelines to induced AC voltages which is a real and serious problem which can place both operator safety and pipeline integrity at risk. In case of a lightning stroke on power line, the electromagnetic field produce by this pulse induces voltages in the nearby metallic structures. In this paper lighting stroke to transmission line sky wire and phase conductors and its impact on a nearby underground metallic pipeline were studied. EMTP-ATP in combination with ATP-Draw has been used to create a model of the system and to perform simulation of the transient process during lighting strike and compute the induced voltages in the metallic pipeline. 
