1. Introduction to Electrical Transformers

Electrical transformers are essential devices that facilitate the transfer of electrical energy between circuits at different voltage levels. They serve as critical components in the electricity supply chain, ensuring that power can be efficiently transmitted from power stations to industrial facilities and eventually to consumers.

2. How Transformers Work

Principle of Electromagnetic Induction

Transformers operate on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a nearby conductor.

Transformer Construction

A typical transformer consists of two or more coils of wire wound around a laminated iron core. These coils are known as primary and secondary windings.

Transformer Core and Windings

The iron core provides a low-reluctance path for the magnetic flux, and the windings are where the primary and secondary currents flow.

Types of Transformers

Transformers can be categorized into various types, including power transformers, distribution transformers, and instrument transformers, each designed for specific applications.

3. Step-up and Step-down Transformers

Step-up transformers increase the voltage level from the primary to the secondary winding, while step-down transformers decrease the voltage level.

4. Functions of Transformers in Industrial Applications

Voltage Transformation

Transformers are crucial for voltage transformation, allowing electricity to be transmitted over long distances with reduced losses.

Current Transformation

In industrial applications, transformers can transform current levels to match the requirements of specific equipment.
