Introuction

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.
