Components of Power Transformers
- Core Components: The core often made of laminated steel sheets and forms the magnetic path and facilitates efficient flux linkage.
- Windings in Power Transformers: The Primary and secondary windings enable voltage transformation.
- Insulating Materials: The Insulation between windings and components prevents short circuits.
- Tap Changer: A device to modify the turns ratio and adjust output voltage.
- Bushings in Transformers: The Insulated entry/exit points for the external connections.
- Transformer Tank: The Encases core, windings and other vital components filled with the oil for the insulation and cooling.
- Conservator Component: The Manages oil level variations due to temperature changes.
- Breather Component: The Regulates air exchange to prevent moisture buildup.
- Cooling System: To Keeps transformer temperature within the limits.
- Explosion Vent: To Ensures safety by releasing excess pressure during the faults.
- Buchholz Relay: To Detects internal faults by the analyzing oil flow and gas accumulation.
