Operation & Maintenance of Circuit Breakers & Switchgears



Introduction:


The duty of a circuit breaker is to switch on and switch off, once or repeatedly several times different electrical circuits during normal as well as abnormal operating conditions. Circuit breakers and switchgears specification, operation, testing and maintenance are essential for engineers and technicians. This course designed to provide the participants with technical knowledge, practical experience and good skills in the field.

 

This course will provide delegates a solid understanding on the safe use of circuit breakers, switchgears and associated equipment that requires correct initial selection, operation and maintenance. Strong emphasis on detailed understanding of how these devices should be installed, the local substation and system ratings, and how the various breakers operate; in order to enable accurate troubleshooting and subsequent repair.

You will enhance skills to ensure that circuit breakers and switchgear are installed, operated safely and maintained in a fashion that ensures safe and stable operation. Delegates will be exposed to recognize faults and ensure the underlying causes are identified to reduce possible further failures. This course will feature:

 

  • Understanding the types and functions of circuit breakers
  • Operation principle of medium voltage circuit breakers
  • Identification of testing equipment and instruments
  • Interpretation of single line drawings
  • Troubleshooting and maintenance of switchgears

Course Objectives:


 By the end of this course, delegates will be able to:

 

  • Understand the arc phenomena and circuit interruption
  • Know the different types of circuit breakers and industrial switchgears
  • Understand the various types and operations of circuit breakers
  • Determine the components and operations switchgears
