What are the different types of transformers and their applications? Greetings to all the electrically inclined folks! Today, we’re going to unlock the mystery behind the vital players in our electrical network – Transformers. These ubiquitous entities come in an array of types, each with its own unique features and uses.
The Backbone of Transformers
In their simplest form, transformers act as electrical devices that facilitate the transfer of electrical energy from one circuit to another using electromagnetic induction. To comprehend them fully, it is indispensable to have a fundamental understanding of Faraday’s Law of electromagnetic induction.
Types of Transformers
Based on the core medium and applications, we can categorize transformers into several types:
1. Power Transformers: They are typically seen in power generation stations and transmission substations. They are mainly used for the transmission of power.
2. Distribution Transformers: Mainly used in the power distribution network, these facilitate the final voltage transformation in the electric power distribution system.
3. Instrument Transformers: These consist of current transformers and voltage transformers and are primarily used for measurement and protective relay operations in the electrical power industry.
4. Isolation Transformers: Isolation transformers are used to decouple two circuits, allowing AC signal and power transfer while blocking transmission of DC signals.
5. Autotransformers: Here, a single winding acts as both primary and secondary, saving on cost and weight. Applications include starter motors and power applications.

The Flip Side
Just as with any device, transformers also come with a set of limitations. While they serve as efficient power transfer units, they can also suffer from losses like copper and iron losses. Furthermore, size and cost increase with the capacity of the transformer.
