Unit Description and General Aims

The objective in presenting this unit is to impart to students relevant knowledge of the essential supporting infrastructure and systems of industrial and other enterprises. The subject matter covered in this unit will include the basic principles of: earthing, shielding, and cabling best practices; power generation and distribution; and, motor technology – protection, control, and maintenance. Power generation will be examined by means of boiler operation and control. The fundamentals of power distribution will be examined through a detailed evaluation of means of cabling, transformers, earthing, and distribution simulations. The unit further provides the student with the knowledge of boiler processes and control functions, along with the related instrumentation. p>
