In today’s world, electrical power is used to help us do much of our work and make our lives more livable and enjoyable. Individually, most of us only use single-phase power. However, for industrial and commercial purposes, three-phase power is the predominant way that electrical energy is generated, transmitted, and used. With that in mind, it can be useful to know some of the basic theory of three-phase electrical power.
In this course, you will learn the basic concepts of single-phase and three-phase alternating current electrical power. We will start with single-phase electrical theory, because three-phase voltage is simply three single-phase voltages connected in a certain manner.
This course is set up so that any engineer can gain a better understanding of how the power and energy that we use operate. Afterward, you may begin to notice the transmission lines and electrical switchyards that are scattered over the landscape.
Special Note: Course E-2058 and the webinar E-2023W are alternate presentations of the same course material. Therefore, only one version can be taken during a renewal cycle. If you have any questions regarding course eligibility, please contact our Customer Service Team.
