Here are five training courses about transformers, basic concepts of electricity, and how power is distributed. Each course consists of approximately 100 slides, with audio.

These practical training courses were developed by Gordon Solee. The voice is Mr. Solee himself, recorded during an actual presentation.

You might want to take each course several times. First, go through the material, learning what comes easy. Then, return to focus on the more difficult sections.

After a course downloads to your computer, you can advance to any spot in the program by moving the slide-bar below the video.

These courses are also available as a printed book.
