epd.wisc.edu/RA01357 See upcoming dates

Course Overview

Upon completion of this course, you will understand:

  • Applicable design and equipment standards, guide documents and other valuable technical reference materials, and where to locate them.
  • The fundamentals of traction power substation, distribution system and overhead contact system design, construction and operation
  • Traction power load flow simulation methods, input requirements and available software for AC and DC traction power systems
  • Traction power wayside energy storage systems, substation grounding and substation automation/control

Who Should Attend?

This course introduces many of the fundamentals of rail traction power and overhead contact systems. If you work in this area or need to understand the concepts related to electrically-powered rail systems, this is the course for you. Although this is a "fundamentals" course, it will be most beneficial to attendees who have at least a limited knowledge of the topics of electrical traction power.
