DESCRIPTION

Circuit breakers, fused switches and switchgear in the form of motor Control Centres (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 & 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

OBJECTIVE

Understanding of the operational characteristics of circuit breakers and switchgear.
Understanding of troubleshooting procedures, as applied to circuit breakers and associated switchgear.
Improved capability in the use of test equipment.
Better understanding of failure modes and failure analysis as applied to fuses, circuit breakers and switchgear. In relation to air break, vacuum and SF6 devices.
Refreshed awareness of electrical safety concerns within substations and control centres.
Ability to determine fault levels in substations.

WHO SHOULD ATTEND

Electrical Engineers
Electrical Supervisors and
Senior Electrical Technicians engaged in the operation, maintenance and troubleshooting, of circuit breakers, interruptive devices and switchgear control centres.
