Electrical Engineering Applications with the TI-89
This book is written for electrical engineering students. It is a collection of examples that show how to solve many common electrical engineering problems using the TI-89. It is not a textbook; if you do not know how to solve the problem, look it up in your textbook first. If you do know how to solve the problem, this book will show you how to use the TI-89 to get the answer with more insight and less tedium. We show you how to use the TI-89 in class, in lab, on homework, and so forth.
shows how to handle phasor algebra, complex power, power factor corrections, and unbalanced three- phase calculations using the TI-89.
The sinusoidal, single-frequency voltages and currents of power systems are usually written as phasors â complex numbers in magnitude and phase form. This form is particularly useful in three-phase calculations when phasors must be added or subtracted. For Y-configurations, the line-to-neutral voltages, van, vbn, and vcn, (often called the phase voltages) are combined to give the line-to-line voltages, vac, vba, and vcb as shown in Figure 1.
To be sure the functions are entered correctly, graph them. This book follows the standard electrical engineering convention of writing these as functions of time, t . The TI-89, however, displays graphs as functions of x .
