Course Syllabus

Course Description

This course is designed to update participants with the latest development of Circuit Breakers and to present some of the more common and updated aspects of low, medium and high voltage switchgear maintenance. It must be understood that there is an incredible variety of equipment used on low, medium and high voltage switchgear today. Switchgears play an important role in the distribution and control of electrical power in manufacturing or power plant and in a utility distribution system. Negligent maintenance practices can lead to power system inefficiency and loss of system reliability.

Course Objective

This course is designed to enable participants to:

  • List the voltage convention classifications used in this course.
  • Describe switchgear construction.
  • Describe a ground fault relay system.
  • Describe the three basic types of low and medium voltage circuit breaker contacts.
  • Describe the molded case circuit breaker.
