Transformer
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It is used to change the voltage levels in alternating current (AC) electrical systems, enabling efficient transmission and distribution of electrical power over long distances. Transformers are fundamental components in power systems, electrical distribution networks, and many other applications.

Key Components of Transformers

  1. Primary Winding: The coil or winding connected to the input voltage source. The primary winding creates the magnetic field that induces voltage in the secondary winding.

  2. Secondary Winding: The coil or winding that receives the induced voltage from the primary winding. The secondary winding provides the output voltage to the connected load.

  3. Core: The magnetic core is made of ferromagnetic material, such as laminated steel or iron. It provides a path for the magnetic flux generated by the primary winding and enhances the efficiency of the induction process.

  4. Insulation: Insulating materials are used to separate the windings and core to prevent electrical short circuits and ensure safe operation.

  5. Tap Changer: A device that allows for adjusting the turns ratio of the transformer to change the output voltage. Tap changers are used for voltage regulation and maintaining stable output voltage.

  6. Cooling System: Transformers generate heat during operation, and cooling systems, such as oil-filled or air-cooled systems, are used to dissipate this heat and maintain optimal operating temperatures.
