This training course will benefit all levels of professionals in an electrical installation. It will enable them to understand the importance of safe operations of circuit breakers and switchgear
This training course is suitable for a wide range of technical professionals but will greatly benefit:
This training course will provide delegates with a solid understanding of the safe use of circuit breakers, switchgear and associated equipment that requires correct initial selection, operation, and maintenance. Strong emphasis on a 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 training 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 switchgear
Objectives
By the end of this training course, participants will be able to:
Understand the various types and operations of circuit breakers
Determine the components and operations switchgear
Explain the different types of testing instruments
Analyze the common faults in an electrical installation
Inculcate greater confidence, working safely on circuit breakers and switchgear
Methodology
This training course will utilize a variety of proven adult training techniques to ensure maximum understanding, comprehension, and retention of the information presented. This includes presentation and discussion of the 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.
