Here we comes with 12 types transformers:

1. Power Transformers

Designed for high-capacity power transmission in electrical grids. Usually operate at very high voltages and handle large amounts of power.

2. Distribution Transformers

Smaller than power transformers, these are used to step down the voltage from the distribution lines to levels suitable for consumer use, typically found near residential or commercial areas.

3. Instrument Transformers

*Current Transformers (CT): Used to measure or monitor high-level currents in a circuit by stepping down to safer and more manageable levels for meters and protection devices.

*Potential Transformers (PT): Similarly, they step down high voltages to measurable levels for safe metering, relaying, and control purposes.

4. Autotransformers

A single winding transformer where part of the winding is common for both primary and secondary. They are efficient for small voltage changes and can be used for power transmission and motor starting.

5. Isolation Transformers

Primarily used to provide galvanic isolation between two circuits, preventing direct current flow while allowing AC signals or power to pass. They are crucial for safety and noise reduction in sensitive equipment.

6. Three-Phase Transformers

 Designed to work with three-phase power systems, these can be constructed as either three separate single-phase units (bank) or a single unit with three sets of primary and secondary windings.

7. Single-Phase Transformers

Used for single-phase power supplies, commonly found in residential and light commercial applications.

8. Dry-Type Transformers

These transformers use air or pressurized gas for cooling instead of oil, making them safer for indoor installations and environments sensitive to oil spills.

9. Oil-Filled Transformers

Utilize oil as a coolant and insulator. They are more efficient for larger capacities but require careful handling due to fire and environmental hazards associated with oil.

10. Toroidal Transformers

Characterized by a doughnut-shaped core, they offer high efficiency, low external magnetic fields, and compact size, making them popular in audio equipment and other applications where space and noise are critical factors.

11. Resonant Transformers (Frequency Changers) 

Specialized transformers used to change the frequency of alternating current, often employed in power conversion systems.

12. Audio Transformers

Designed specifically for audio applications to match impedances, isolate circuits, or split signals without significant loss of quality.
