Transformer Application Fundamentals gives the reader a working knowledge of the important aspects of transformers, how they work, and how to apply them without getting deep into theory or mathematics. The simplified approach used is based upon “need to know” rather than knowledge for the sake of knowledge.
Completion of this course will be of little help in designing transformers, however it will be of great assistance in selling and applying transformers.
This text must be studied. All of the text should be read, the problems worked and the questions answered, if you are to receive full benefit. The course is designed to make learning enjoyable and as effortless as possible, but the reader must be prepared to work as well.
The points of importance are generally covered in the direct questions and the review questions. If you can choose the correct answers you probably have a good grasp of the important points. If you should find a particular point hard to understand, it is suggested that you also read the wrong answer response pages. These pages often carry additional information which will clear up the subject in question.
This has been written with the assumption that the reader is already well versed in basic electricity. If not, it is recommended that a basic electricity course be completed before proceeding.
A foundation for further study in the field of specialized transformer applications is provided.
Do not attempt to read this as you would an ordinary post. The pages are numbered consecutively, but they are not to be read this way. At the bottom of each page is an instruction indicating which page you are to read next. It may be forward or backward, so follow instructions carefully.
This text is “programmed” and makes use of branching programming (where you go to a different page for more information) and linear programming (where a question is asked and you will find the answer close by).
The course functions as a personal teacher. It gives you information and asks questions frequently. When you miss a question the correct answer is given, plus additional information which will assist you to under stand before proceeding to new material.
We suggest short sessions–one chapter at a session. This approach will be most productive. Take your time and study carefully, being sure to follow instructions.
Here are brief descriptions and links to the chapters of the course.
