The Distribution Line Safety course is designed primarily to introduce participants to principles and techniques of equipotential grounding. Although the course is intended as an introduction to equipotential grounding, the procedures and concepts presented assume a familiarity with basic electrical theory, distribution systems, grounding theory and application, and basic distribution line work methods and procedures. Participants without this prior training may require additional explanation or instruction.

At the conclusion of this course, participants should be able to explain the purpose of grounding an overhead line during maintenance work and describe ways in which an isolated or de-energized line can become energized. Participants should also be able to define the term “zone of equipotential” and explain how equipotential grounding operates to safeguard linemen in the event of a ground fault condition. Finally, participants should be able to describe or demonstrate how grounding equipment can be used to set up a zone of equipotential.
