TRAINING COURSE:
Distribution Line Safety
Course Category: Transmission and Distribution
Course description: 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.
Course syllabus:
- Grounding
- Define the terms “energized,” “isolated,” and “de-energized” with respect to overhead line work
- Describe ways in which an isolated or de-energized line can become energized
- Describe a typical procedure used to ground an isolated overhead line
- Equipotential Grounding
- Use Ohm’s law to describe current flow in a de-energized overhead line during a ground fault condition
- Define the term “zone of equipotential”
- Describe a method that can be used to establish a zone of equipotential
- Equipotential Grounding Connections
- Describe how grounding equipment can be used to create a zone of equipotential on a three-phase overhead line
