Designed as an introduction to 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. 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.
