This course will equip you with the principles and theory of single-phase transformers. A transformer is a static device that converts electrical power from one circuit to another at the same frequency. First you will learn how the principle of mutual induction of coils in transformers works and all about what primary and secondary windings are. Then we will demonstrate the electromagnetic fields (EMF) equation the turns ratio of transformers how to represent waveforms and vectors and equivalent circuit diagrams. We will also look at the open circuit characteristics of transformers and the effects of voltage and frequency changes. Want to know about energy losses in transformers and how to deal with them? The two most important losses in transformers are iron and copper. 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. We explain this entire process and the two main types of transformers you differentiate by their construction: core and shell transformers. Then you will learn about the importance types and properties of insulating oil used in transformers. Do you wonder how configurations of three-phase transformers work in star and delta combinations? We will also explain these topics. You'll learn about centre-tapped transformers and the Scott or TT connections used when working with two-phase power. Next we will look for insight into the series-parallel connection of transformers and the effects of incorrect parallel connection.Then the course will take you through the various tests including ratio testing open circuit testing and short circuit testing. You will learn what ‘voltage regulation’ is and how efficiency testing works in transformers. You will further examine the winding polarity and core balance testing. You will also explore 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 the particular requirements for designing marine transformers. This course is ideal for those who want to gain knowledge in the use and construction of transformers.
