Electromagnetic Interference (EMI)<\/strong> produced by High Voltage AC power supply systems and AC traction systems is a rigid concern for nearby buried metallic pipelines. The main concern lies with electrical hazards to people in contact with the pipelines\u2019 exposed parts. Other adverse concerns are ranging from accelerated corrosion to pipelines\u2019 failure. To this extent, many international standards are providing safety limits, relevant to the interference that can be tolerated on the metallic pipelines. These limits primarily refer to the total acceptable interference voltage produced on pipelines, by the normal operating conditions of all nearby AC interfering sources (i.e. overhead lines, power cables, electrified railway systems). Within these standards, there is also an explicit reference to the acceptable interference voltage limits that apply, when the fault conditions, of a single AC interfering system acting alone, are considered. Nonetheless, estimating AC interference on pipelines is a complex problem with multiple interacting variables, affecting both the impact and consequences. This necessitates specialist knowledge in the fields of pipelines\u2019 protection and in earthing\/grounding practices.<\/p>\t\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div><\/div>\r\n\t\t<\/section>\r\n\t\t\t\t
