“Far exceeded my expectations. Taught by true professionals in their industry.” COO, Universal Electric

This course will introduce and provide non-technical people with the basics of the overhead distribution system and all the general components that make up the system. Issues that are involved in the design, construction, operation, reliability, protection and maintenance of overhead distribution, as well as safety awareness will be discussed.  It will allow people who are not distribution engineers to know enough to oversee projects or simply have a better understanding of the system.

Learning Outcomes

  • Review the power system from generator to customer and where distribution fits in
  • Discover how a distribution system works and system configurations
  • Expand on the functions of the system through reliability, power quality, protection and voltage regulation
  • List the various equipment components that make up the system
  • Review the what, the why, and the how of system construction
  • Discuss the operation considerations of protection, reliability and safety
  • Explain the differences in a comparison of overhead and underground systems
  • Explore challenges in system operation
  • Review utility approaches to improving reliability
  • Discuss methods and practices for modernizing the overhead distribution system
