Introduces the fundamentals of 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.
- 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 underground switching equipment including procedures utilized for isolating and in-line replacement.
- Identify safe isolation for work and maintenance of distribution underground 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 a underground distribution circuit.
- Underground cable splicer
- Field service representatives
- Storm assessment personnel
High Voltage Electrical and Physical Hazards (shock, falling/tripping). All PPE (safety glasses, gloves, steel toe boots, fire retardant clothing, insulating tools, etc.) must be properly utilized to prevent injury, exposure, and/or death.
Students must apply for entry into the Power and Trades Pathways Pre-Apprenticeship: Underground Cable Splicer certificate. Applications to the program are available in the School of Business, Entrepreneurship, and Professional Development Office. Students undecided of which Pre-Apprenticeship program they may be interested in should select the Power and Trades Pathways Core Certificate and meet with a subject matter expert in the School of Business, Entrepreneurship, and Professional Development.
