The purpose of this course is to teach how to go about patrolling overhead lines. The importance of patrolling to reliable operation of the lines is discussed, and examples of structure, hardware, conductor, insulator, and obstruction problems are shown and explained. An example of how to detect problems while patrolling an overhead line is also given.

At the conclusion of this course, participants should be able to explain why patrolling overhead lines is important. They should understand the types of problems to look for when patrolling overhead lines. They should be able to detect structure problems, problems with broken or damaged hardware on a pole or tower, problems with conductors and insulators, and current or developing obstructions of the lines. They should also be able to demonstrate the ability to detect problems when patrolling overhead lines.
