The purpose of this course is to teach how overhead capacitors and voltage regulators work, how to detect problems in their operation, and how to safely replace them if necessary. To accomplish this, the course presents the basic theory and operating characteristics of overhead capacitors and voltage regulators and demonstrates how they can be safely replaced.

At the conclusion of this course, participants should be able to describe the function and operation of overhead capacitors, how to detect operating problems, and how to replace an overhead capacitor safely. They should also be able to describe the function and operation of overhead voltage regulators, how to detect voltage regulator problems, and how to safely replace an overhead voltage regulator.
