Parts of Power Transformer and their Functions

1. Core: The core is the central part of the transformer that is made up of laminated steel sheets. It provides a path for the magnetic flux to flow through.

2. Windings: The windings are the two sets of copper wire coils that are wound around the core. One winding is called the primary winding, and the other is the secondary winding.

3. Insulation: The insulation is a layer of insulating material that is used to separate the windings and prevent them from touching each other.

4. Tank: The tank is the outermost part of the transformer that contains the core, windings, and oil. It is made of steel and is designed to withstand high pressures.

5. Tap changer: The tap changer is a device that is used to change the number of turns in the primary or secondary winding. It is used to adjust the voltage of the transformer.

6. Bushings: Bushings are devices that are used to connect the transformer to the power grid. They provide a safe and reliable means of connecting the transformer to the power lines.

7. Oil: Oil is used as a coolant and insulating medium in the transformer. It helps to cool the windings and prevent electrical breakdown.

8. Cooling system: The cooling system is used to regulate the temperature of the transformer. It includes fans, radiators, and other components that help to dissipate heat.
