Course overview
What is AC interference? What is it caused by? What is the mitigation of AC interference?

This course is appropriate for pipeline, utility, and consulting engineers and other technical individuals with the responsibility of AC interference control on pipelines.
The AC Interference and Mitigation webinar is offered as a 6.5-hour course 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.

The objective of this course is for each student to understand the fundamentals of AC interference and AC modeling and mitigation. The webinar is designed to provide the student with knowledge of AC interference and mitigation design.
START TIME: 8:30 a.m.
END TIME: 3:00 p.m.
