This highly informative Safe Operations & Maintenance of Circuit Breakers & Switchgears training course emphasises on the new technologies of medium and high voltage circuit breakers. One of the salient innovations is the elimination of sulphur hexafluoride gas to the new green gas for grid, in line with the world’s effort to reduce the carbon footprint. It will also provide delegates a solid understanding on the safe use of circuit breakers, switchgears and associated equipment that requires correct initial selection, operation and maintenance. New vacuum circuit breaker technologies will be discussed to enhance the safety and secured operation of the electrical installation.
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 and continuous operation. In this Safe Operations & Maintenance of Circuit Breakers & Switchgears training course, delegates will be exposed to recognize faults and ensure the underlying causes are identified to reduce possible further failures. State of the art testing instruments are discussed focusing on circuit breakers and motors.
This Coventry Academy training course will feature:
Understanding the types and functions of circuit breakers
Operation principle of medium and high voltage circuit breakers
Identification of testing equipment and instruments
Interpretation of single line drawings
Troubleshooting and maintenance of switchgears
What are the goals?
By the end of this Coventry Academy training 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
Who is this training course for?
This Coventry Academy training 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 training course is suitable to a wide range of technical professionals but will greatly benefit:
This Coventry Academy training 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.
