This course is held online over 3 days on the following schedule (All times in Eastern Time Zone):

9:00 am to 5:00 pm Eastern (Will include the usual breaks)

After participating in this course, you will be able to:

  • Apply your knowledge of the fundamentals of the utility power supply system and power quality
  • Recognize the important operating characteristics of major power components
  • Improve substation grounding
  • Discriminate between the criteria governing the application of overcurrent and overvoltage protective devices
  • Implement better start-up and regular maintenance of electrical installations

A properly planned and designed substation is essential for the reliable operation of a power system network. A high voltage substation comprises switching equipment, transformers, reactors, var compensators, protection, control, and automation and communication.

This course covers all aspects of high and medium-voltage substation design, including regulatory and environmental requirements, general design considerations, the application of switching and power equipment, fault calculations, safe grounding design, protection/control, automation and communication, and maintenance considerations.

Course Outline:

  • Industrial and utility substation
