Introduction to Transformers

In this free online course, learn about working principles, features, types and properties of transformers

Publisher: ADU
In this course, you will learn in detail the construction, operation and theory of transformers. To do this, we will explore the characteristics, types, and properties of transformer oil. We will then explain the operation of three-phase transformers and the various methods of testing transformers. In addition, you will also learn the working of autotransformers as well as the difference between current and potential transformers.

In this course, Introduction to Transformers, you will learn the principles and theory of single-phase transformers. A transformer is a static device that converts the electrical power of one circuit into electrical power at the same frequency as another circuit. You will learn how the principle of mutual induction of coils in transformers works and what primary and secondary windings are all about. Then you will learn about the equation EMF, the turns ratio of transformers, how to represent waveforms and vectors, and equivalent circuit diagrams. We will also take a look at open circuit characteristics of transformers, the effects of voltage and frequency changes in transformers. Want to know about energy losses in transformers and how to deal with them? This is also explained in this course. The two most important losses in transformers are iron losses and copper losses. An ideal transformer is one in which there are no core and copper losses.

You may be wondering how the construction of single and three-phase transformers works. This course will explain the entire process to you in detail. You will learn about the two main types of transformers that are differentiated by their construction - core transformers and shell transformers. Then you will learn about the importance, types and properties of insulating oil used in transformers. Are you wondering how configurations of three-phase transformers in star and delta combinations work? These topics will also be explained in this course. Then you'll learn about centre-tapped transformers and the Scott or TT connections used when working with two-phase power. Next, we will look insight into the series-parallel connection of transformers and the effects of incorrect parallel connection of transformers.

Then the course will take you through the various tests of transformers, including ratio testing, open circuit testing, short circuit testing. You will also learn what voltage regulation is and how efficiency testing works in transformers? Furthermore, the course will also explain the winding polarity testing and core balance testing. You will also learn how to test transformer oil to determine its dielectric strength? The course will explain the difference between current and potential transformers and how to use them to measure voltage and power. Finally, you will learn what are the special requirements for the design of marine transformers. This course is ideal for those who want to gain knowledge in the use and construction of transformers. So, why wait? Start your learning journey today.
