4 Easy Steps to Complete a PDHengineer webinar

In today’s world, electrical power is used to help us do much of our work, and also helps make our lives more livable and enjoyable. On the personal level, most of us only use single phase power. However, for industrial and commercial purposes, three phase power is the predominate 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 the three phase electrical power.

In “A Simple Way to Look at Three Phase Power” 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.

As engineers, we like to know how the things of the world work. This course is set up so that any engineer can get a better feeling of how the power and energy that we use does the things that it does. Afterwards, you may begin to notice the transmission lines and electrical switchyards that are scattered over the landscape. We may also appreciate the electrical system and view it in a way that we never did before.

Special Note: Course E-3013 and course E-2023W are alternate presentations of the same course material. Therefore, only one version, either the course or webinar, can be taken during a renewal cycle. If you have any questions regarding course eligibility, please contact our Customer Service Team.
