Program Description
Introduces the fundamentals of the theory, skills, and knowledge of the operation and maintenance of overhead electrical distribution systems. Electrical theory application for various distribution line construction and overhead line configurations, energizing and de-energizing techniques, troubleshooting, and grounding of overhead circuits are explored. Single and three phase distribution transformer applications are discussed. Upon successful completion of the program, students will be able to identify and demonstrate personal and electrical safety procedures utilized in overhead distribution switching, isolating, testing and diagnostic applications. Overhead service and power quality issues are analyzed in relation to balanced loading and overall customer satisfaction.
Upon successful completion of this program, students should be able to:
Create an electrical schematic diagram, identifying how connections are made from source to load, including power conductors, single/three phase transformers and switches, and various line protective devices.*
Identify various types of overhead switching equipment including procedures utilized for isolating and in-line replacement.
Identify safe isolation for work and maintenance of distribution overhead line equipment, and explain how they can be isolated utilizing appropriate test equipment.
Define the concepts of lock-out, switching, and tagging, and the proper documentation needed when working on high voltage equipment.
Define sources of electrical and physical hazards at a transformer installation site, and methods of current /voltage protection for working on associated equipment.*
Create an operating sequence for switching to reroute power and isolate a portion of an overhead distribution circuit.
