What Are the Types of Transformers?

There are many types of transformers, which can be classified based on voltage regulation, number of phases, applications, structure, cooling methods, and more.

1. Voltage Regulation:

Step-Up Transformers: Increase voltage.

Step-Down Transformers: Decrease voltage.

2. Number of Phases:

Single-Phase Transformers: Have one phase.

Three-Phase Transformers: Have three phases.

Multi-Phase Transformers: Have more than three phases.

3. Applications:

Power Transformers: Used in power supply systems.

Instrument Transformers: Include voltage and current transformers used for measurement and relay protection.

Impulse Transformers: Used for high-voltage testing of equipment.

Special Purpose Transformers: Include electric furnace transformers, welding transformers, and rectifier transformers.

4. Cooling Methods and Cooling Medium:

Dry-Type Transformers: Cooled by air.

Oil-Immersed Transformers: Cooled by oil.

Water-Cooled Transformers: Cooled by water.

These classification methods allow us to gain a clearer understanding of the characteristics and applications of different types of transformers.
