CDGA

This course depicts the factors to be considered within the area of power generation. It will begin with an overview of generator design and function. Load requirements and calculations including load sharing, shedding and switching will be examined. Power factor calculations and power factor correction techniques will be presented. The techniques and equipment available for monitoring generators will be covered in depth to ensure delegates are made aware of what is available on the modern market and the most appropriate utilization of these systems. The maintenance and protection schemes that are utilized for generation and their applications will be examined. The importance of the roles and responsibilities of personnel working on electrical systems and the safety procedures involved are also explored.
