An oil-immersed transformer is a widely used electrical device designed to transfer electrical energy between two or more circuits through electromagnetic induction. It is commonly utilized in power distribution and transmission due to its efficiency and reliability. One of the key aspects that distinguishes oil-immersed transformers from other types is their use of insulating oil, which serves to cool the transformer and provide electrical insulation. Understanding the main parts of an oil-immersed transformer is essential for maintenance, troubleshooting, and efficient operation. This article explores the fundamental components of an oil-immersed transformer and their respective functions.
1. Core; The magnetic path that links the primary and secondary windings.
2. Windings; Carry input and output currents.
3. Transformer Oil
4. Tank
5. Bushings
6. Cooling System; Help in heat dissipation.
7. Conservator Tank and Breather: Maintain oil level and protect the transformer from internal faults.
8. Tap Changer; Adjusts voltage as per requirement
