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.

On completion, delegates will be equipped or will have enhanced 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

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

• Understand the various types and operations of circuit breakers

• Determine the components and operations switchgears

• Explain the different types of testing instruments

• Analyse the common faults in an electrical installation

• Inculcate greater confidence, working safely on circuit breakers and switchgears

This course will benefit all levels of professional in an electrical installation. It will enable them to understand the importance of safe operations of circuit breakers and switchgears

This course is suitable to a wide range of technical professionals but will greatly benefit:

• Electricians

• Electrical supervisors

• Plant electricians

• Operations & maintenance engineers, supervisors & technicians

• Maintenance technicians

This course will utilise a variety of proven adult training techniques to ensure maximum understanding, comprehension and retention of the information presented. This includes presentation and discussion of latest videos and circuit breaker technologies.

Questions are encouraged throughout, particularly at the daily wrap up sessions. This provides opportunities for participants to discuss with the Presenter specific issues and, if possible, find appropriate solutions. Specific goals of each participant will be discussed to ensure that their needs are fulfilled whenever practicable.
