Understanding 10 Main Parts of a Transformer

Understanding 10 main Parts of a Transformer

Transformers are essential in power systems, efficiently transferring electrical energy between circuits through electromagnetic induction. Understanding their key components helps in better maintenance and troubleshooting. Let’s break it down!

MEP Tolls -10 Main Parts of a Transformer

Main Parts of a Transformer:

1. Core – Made of laminated steel sheets to reduce eddy current losses and provide a path for magnetic flux.

2. Windings (Primary & Secondary) – Copper or aluminum coils responsible for voltage transformation through electromagnetic induction.

3. Insulation – Protects windings from short circuits and electrical breakdown, using materials like oil, paper, or epoxy.

4. Transformer Oil – Used in oil-filled transformers for insulation and cooling, preventing overheating.

5. Tap Changer – Adjusts the number of turns in the winding to regulate output voltage (On-Load & Off-Load types).

6. Bushings – Insulated terminals that allow electrical connections without leakage or short circuits.

7. Conservator Tank – Found in oil-filled transformers, it accommodates the expansion and contraction of oil due to temperature changes.

8. Breather (Silica Gel) – Prevents moisture from entering the transformer oil, keeping it dry and efficient.

9. Cooling System – Can be natural air (AN), forced air (AF), or oil-based (ONAN, ONAF) to manage heat dissipation.

10. Protection Devices – Includes Buchholz Relay (for detecting faults), Pressure Relief Valve, and Temperature Gauges for monitoring.

💡 Understanding these components helps in preventive maintenance, reducing downtime, and improving transformer life!
