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.

An older plant may have switchgear that was built in the forties in the older areas and modern switchgear in other areas as the plant was upgraded. This course will present maintenance problems to the maintenance manager and technician. Newer plants will probably have modern equipment of a limited variety and manufacture. It is these similarities that will be covered in the course.

Course Objectives

Towards the end of the training, the participants will be able to:

  • Inspect, maintain, design, repair and troubleshoot circuit breakers and switchgears
  • Apply an in-depth knowledge and skills on LV/MV/HV circuit breakers and switchgears
  • Describe the switchgear details such as ratings, degree of protection, service conditions and ancillary equipment
  • Explain switchgear asset management including CBM & RCM process, tripping devices, maintenance & testing and identify the various switchgear diagnostic techniques
  • Identify & employ the different types of circuit breaker techniques and determine the switchgear vital equipments including batteries condition and monitoring
  • Employ the substation maintenance techniques and discuss their description, structures, features and functions
  • Apply the switchgear maintenance practices and improve maintenance and repair procedures
  • Carryout maintenance work orders including their process development, procedures and problems encountered
  • Introduce computerized maintenance management systems (CMMS) and recognize its importance in circuit breakers inspection, maintenance, design, repair & troubleshooting
