What are the 14 parts of a transformer?

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It consists of several key parts, each serving a specific function in its operation. Here are the 14 parts commonly found in a transformer:

 1. Core

   - The core is made of laminated silicon steel and serves as the pathway for magnetic flux. It provides a low reluctance path for the magnetic field and minimizes energy loss.

 2. Windings

   - Primary Winding: Connected to the input voltage source and creates the magnetic field in the core.

   - Secondary Winding: Connected to the output and receives the induced voltage from the primary winding.

 3. Conservator

   - It is a tank located at the top of the transformer and serves to accommodate the expansion and contraction of transformer oil due to temperature changes.

 4. Breather

   - Contains silica gel that absorbs moisture from the air entering the conservator to prevent contamination of the transformer oil.

 5. Buchholz Relay

   - A gas-operated protection relay that detects faults in the transformer, such as gas accumulation or sudden oil flow.

 6. Tap Changer

   - Allows for adjusting the transformer voltage by changing the turns ratio. It can be either off-load or on-load.

 7. Cooling Tubes/Radiators

   - Provide surface area for heat dissipation from the transformer oil to the ambient air, helping to keep the transformer cool.

 8. Transformer Oil

   - Serves as both an insulating material and a cooling agent, helping to maintain the transformer's temperature and insulation quality.

 9. Bushings

   - Insulated devices that allow safe passage of current-carrying conductors through the transformer tank, providing electrical insulation.

 10. Magnetic Shield

   - Installed to reduce the effects of external magnetic fields and prevent eddy currents in non-magnetic materials.

 11. Pressure Relief Device

   - Protects the transformer by releasing excess pressure generated inside the tank due to internal faults.

 12. Oil Level Indicator

   - Shows the level of transformer oil in the conservator to ensure adequate cooling and insulation.

 13. Temperature Gauge

   - Monitors the temperature of the transformer winding and oil to prevent overheating and ensure safe operation.

 14. Oil Surge Relay

   - Detects sudden movement of oil caused by internal faults and triggers protective actions.

These parts work together to ensure the efficient and safe operation of a transformer.
