Fundamentals of Underground Electrical Distribution Systems, March 11-12, 2020 in Toronto, ON

This training program will introduce basic and advanced concepts of the overhead distribution system and all the associated components that make up the system. The course covers all aspects and issues that are involved in the design, construction, operation, reliability, protection and maintenance of overhead distribution, as well as safety awareness. There are sections of the course that cover the operability aspect, the challenges and role of the Distribution System Operator, communication and control, normal and emergency operation and service interruptions that impact the distribution system, and the end customer and how to manage the challenges. It will enable engineers and operators to gain the knowledge required to have a better understanding of the distribution system.

The course material will be a useful resource for future reference and is designed to stimulate dialog between the attendees and the instructor. A prior background in the Power & Utilities industry is recommended. 

Learning Outcomes  

  • Review the power system from generator to customer, where distribution fits in, how the distribution system works, and system configuration
  • Expand on the functions of the system through reliability, safety, power quality, protection and voltage regulation
  • List the various equipment and components of the distribution system
  • Review the what, the why, and the how of system construction
  • Explain the differences in a comparison of overhead and underground systems
  • Explore challenges in system operation associated with communication, control, normal and emergency operations, and service interruption
  • Review utility approaches for enhancing reliability and transformation of the distribution system
