The Pipeline AC Interference and Mitigation course is offered as a 2-day course, ending at 3 on the second day, that covers the principles of AC interference and mitigation on pipelines. This course addresses the basics of AC circuits, AC interference, how to predict the effects of the AC interference on pipelines, and current methods and equipment used in AC mitigation. Course topics include the basic principles of AC circuits, induced AC pipeline voltages, shock hazards, AC corrosion, fault conditions, AC modeling, AC mitigation, and AC measurement techniques. This course utilizes a combination of theory and practical information and includes AC modeling and mitigation examples.

"Very knowledgeable instructor."
