        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
      particular audience. Introduction Comprehensive

 Introduction  Study 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. Overview 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
        safety. 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. 
 Considerations In addition to technology, the design
        and installation of any electrical system must consider
        three major items - safety, environment, and cost. |
