overview is to give a flavor of the custom seminars and
manuals. It includes excerpts from
the introduction along with table of
contents from two different courses - a
comprehensive and a topical structured for a
Electrical power costs are about
one-third of industrial production operating costs. They
represent a major part of most industrial companies
operating budget. Furthermore, electrical operations
receive very little attention in proportion to their
impact. Moreover, most operations are critically
dependent on electrical energy. Whether for motors,
computers or environmental systems electricity has become
the most used and flexible energy form.
The major reasons that study of
electrical system is shunned are three fold. The first
reason is fear because of the perceived hazards
associated with electricity. The second obstacle is lack
of understanding of the fundamental theory. The third
hurdle is electrical concepts must be explained by
nebulous models. One cannot taste, smell, see, hear, or
touch the stuff without significant hazard.
Nevertheless, a good grasp and working
knowledge of the electrical fundamentals can be obtained
without being a graduate electrical engineer. This
presentation will be made in outline form to assist
future quick reference.
The outline covers equipment from the
top of the pole to the bottom of the hole. Every
electrical power circuit has the same form. The items of
discussion will be basic terminology, application, and
A typical power system is shown in the
figure. Electrical systems always convert an available
energy source to electrical energy. The electricity is
then conveniently transferred to a load which converts
the electrical energy back to another energy form.
In addition to technology, the design
and installation of any electrical system must consider
three major items - safety, environment, and cost.
