Safe Operation & Maintenance of Circuit Breakers & Switchgears
Introduction:
Circuit breakers, fused switches and switchgear in the form of motor Control Centers (MCC) are necessary system items for the electrical control of electrical plant. The safe use of these devices and associated equipment requires correct initial selection, operation and maintenance. It is also necessary to have 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. Safe Operation and Maintenance of Circuit Breakers and Switchgear will equip participants with new or refreshed skills to ensure that circuit breakers and switchgear are installed, operated safely and maintained in a fashion that ensures safe and stable operation. Also they will be able to identified faults and ensure the underlying causes are identified to reduce possible further failures.
Course Objectives:
By the end of this course delegates will be able to:
· Greater personal confidence in approaching working safely with power switchgear
· Understanding competence and Health and Safety at work
· Awareness of the fault level and fault currents within equipment
· Detailed understanding of the various interrupting mediums, air, vacuum and SF6
