A fault on a power transmission line that is near a pipeline can cause direct or non-direct arcs at defects in the pipeline coating, which can melt the pipe steel and cause a crater in the pipe wall. This paper outlines a procedure for predicting such fault-related pipeline damage, based on published controlled test data for direct and indirect arcs. Examples are provided to illustrate the results for a studied pipeline exposure.
