With energy resources becoming scarce and costly, and electrical energy being the most sought after form of energy, the designers of electrical systems are faced with the challenge of guaranteeing energy efficiency, quality and scheduling to the satisfaction of the corporate customers. This demands that the electrical systems designers to be more versatile and more effective managers of energy resources. This data handbook is intended to be used as design assistance to the beginners in the field of Electrical Systems design and provides them an easy access to the relevant data required for their design without having to waste their time and energy in searching for the required data to be used in the design problem.
This design data handbook is not intended for specialists in the field, but rather for the students of Electrical Engineering who are just entering the field of electrical systems design. This handbook also does not show the student how to be a designer, but presents in a concise manner the basic reference data to perform the design functions. This handbook can be permitted to be used inside the examination hall as a reference handbook.
