Under fault conditions on the powerline, the pipeline potential can reach thousands of volts. which is considered as a safety issue. In addition to the risk of AC corrosion in case of small coating damage.
My questions are
1- is this minimum distance depends on the liquid service (Oil, Gas or Water)? In other words, can this minimum distance reduced if our pipeline transports water rather than oil or Gas?
2- And in case of water transmission line (3LPE externally coated), what is the minimum horizontal distance between a pipeline and overhead powerline supports? Provided that our overhead powerline supports is 60 KV (can anyone please help me with finding a reference for that?)
3- And in case if the minimum horizontal distance between a pipeline and overhead powerline supports is less than the minimum recommended distance, what can we do to mitigate such a problem?
