What are the parts of transformers

Question

Accepted Answer

Transformers consist of several key parts that enable the conversion of electrical energy from one voltage level to another.

Core: Provides a path for magnetic flux and is usually made of laminated steel.
Windings: Consist of primary and secondary coils that are wound around the core.
Insulation: Prevents electrical leakage and ensures safety.
Tap changer: Allows adjustment of the transformer's output voltage.
Cooling system: Keeps the transformer from overheating, commonly using oil or air as a coolant.
Bushings: Provide electrical connections for the transformer.
Conservator tank: Stores oil and compensates for oil expansion and contraction.
Breather: Controls the moisture level inside the transformer.
Buchholz relay: Detects faults such as internal short circuits or oil leaks.
Winding temperature indicator: Monitors the temperature of the windings.
Oil level indicator: Indicates the level of oil in the transformer.
Pressure relief device: Releases excess pressure to prevent damage.
Terminal connectors: Connect the transformer to the electrical system.
Grounding system: Ensures safety by providing a path for electrical faults to the ground.
