In this article, we will learn about what is an ideal transformer.
Definition of Ideal Transformer
An electrical transformer is said to be an ideal transformer when:
- It has no winding resistance i.e., an ideal transformer has zero resistance of its primary and secondary windings. Hence, there is no I2R or copper loss in the ideal transformer.
- It has no leakage flux i.e., the magnetic flux produced by the primary winding completely links to the secondary winding.
- It has no iron or core losses i.e., the losses that occur in the magnetic core which are eddy current loss and hysteresis loss are zero for an ideal transformer.
Diagram of Ideal Transformer
The schematic diagram of an ideal transformer is shown in the following figure.
From this diagram, we can observe that
$$V_1 = E_1$$
$$V_2 = E_2$$
Conclusion
So, this is all about the definition and diagram of an ideal transformer. An ideal transformer does not exist practically, but it is a model of a transformer used for the study and analysis of a practical transformer.
