Damage to a pipeline system and/or danger to pipeline personnel are potential electrical effects when there is an a-c transmission line in proximity to the pipeline (conduction of stray currents, ground currents, lightning) or parallel to the line (induced voltages). Fault conditions in the transmission line give momentary high voltages in pipes which are aboveground or electrically insulated by protective coatings. Damage may result to cathodic protection systems, coatings, or the pipe. High voltages are the result of combinations of a large number of factors. The complex relationships among these factors are set forth together with recommendations for avoiding or mitigating troublesome or dangerous situations.
