Introduction
This highly informative training course emphasizes on the new technologies of medium and high voltage circuit breakers. One of the salient innovations is the elimination of sculpture hexafluoride gas to the new green gas for the grid, in line with the world’s effort to reduce the carbon footprint. It will also provide delegates a solid understanding of the safe use of circuit breakers, switchgear, 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. 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 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 switchgear
Objectives
- 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
Upon successful completion of this course, the delegates will be able to:
Training Methodology
This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
