DESCRIPTION - summary of the module content
AIMS - intentions of the module
This course employs a theoretical, practical, multidisciplinary approach to provide introductory students with a broad understanding of electrical machines, measurements and control of electric energy. The course is considered as a foundation for the Network Engineering, Modelling and Management module in the third year for BSc in Renewable Energy, or as a “stand-alone” basic course in electrical engineering as part of mining engineering degree courses.
INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)
