ABSTRACT
This chapter lays the groundwork for the study of electric energy systems and develops some basic tools involving fundamental concepts, definitions, and procedures. It can be considered as simply a review of topics utilized throughout this work. The chapter begins by introducing the principal electrical quantities. Generally, the electric power systems specialist is more concerned with electric power in the circuit rather than the currents. The value of instantaneous power flowing into an element is the product of voltage across and current through it. It seems, then, reasonable to exchange the current for power without losing any information. Single-frequency alternating currents are fed into the stator circuits and the rotor circuits are all short circuited in a conventional induction machine. The International Electro technical Commission, the American National Standards Institute, and the Institute of Electrical and Electronics Engineers have published a set of standard symbols for electrical diagrams.
