Course Overview

The design and maintenance of switchgear play an important role in the supply and control of electrical power in a utility distribution system.

It must be understood that there is an incredible variety of equipment used on low, medium and high voltage switchgear today and careless maintenance practices can lead to power system inefficiency and loss of system reliability.

Therefore, this course is designed to inform participants of the latest development of circuit breakers and present the common and modern-day aspects of low, medium and high voltage switchgear design and maintenance.

What themes will be covered in this “Design, Maintenance of High, Medium and Low Voltage Switchgear” course? The focus of this program will discuss fundamentals of circuit breakers, types of low and medium voltage circuit breaker, HV, switchgear, insulation and maintenance of CB, over current trip equipment, and the testing of low and medium CB.

This Zoe training course will empower you with knowledge in the transient phenomena of power systems and the methods of system earthing and protection requirements.

Course Objectives

Upon completing this course successfully, participants will be able to:

  • Demonstrate the components of different voltage switchgear
