6.1 UTILIZATION OF ELECTRICAL ENERGY
L P
5 –
RATIONALE
This subject assumes importance in view of the fact that a diploma engineer has to work in a wide
spectrum of activities wherein he/she has to make selection from alternative schemes making technical and
economical considerations; e.g. to plan and design an electrical layout using basic principles and
handbooks, to select equipment, processes and components in different situations. The contents have
been designed keeping the above objectives in view. Besides giving him basic knowledge in the topics
concerned, attempts have been made to ensure that the knowledge acquired is applied in various fields as
per his job requirements. To orient the subject matter in the proper direction, visits to industrial
establishments are recommended in order to familiarize the students with the new developments in
different areas
