Medium-Voltage Electrical Distribution for Mission Critical, Industrial, and Campus Facilities

Upcoming dates (1)

May 6-10, 2024


Course Overview

A practical course that will help expand your knowledge of medium voltage (1kV to 38kV) systems in non-utility applications.

After completing this course, you will better understand the components that make up medium voltage systems used in non-utility applications. You will learn how systems are laid out and how components are designed and selected. You will also better understand reliability and cost trade-offs in design as well as "Over 1000 Volt" installation requirements in the National Electrical Code and other applicable codes.

Who Should Attend?

  • Facility Electrical Engineers & Designers
  • Mission Critical Electrical Engineers & Designers
  • MV Electrical Technicians and Operators
  • Plant Engineers
  • Electrical Contractors
  • Utility Customer-Support Engineers

Additional Information

This course has been approved by the State of WI Department of Safety and Professional Services (DSPS) for 18 hours for: Registered Electrician, Commercial Electrical Inspector, Industrial Journeyman Electrician, Journeyman Electrician, and Master Electrician license holders.
