An oil immersed transformer is a type of power transformer that uses oil as both an insulator and a coolant. The oil absorbs excess heat generated during operation, thereby ensuring that the transformer functions optimally without overheating. This setup makes oil immersed transformers particularly suited for various applications, including connection to generators.
Core: The core is usually made of stacked silicon steel sheets. This design minimizes energy losses and enhances magnetic efficiency.
Windings: Comprised of copper or aluminum, the windings are where the electrical energy transforms from one voltage level to another.
Insulating Oil: The choice of oil is critical for both insulation and cooling. It must have excellent dielectric properties and chemical stability to withstand high temperatures.
Tank: The outer casing that holds the oil, providing protection for internal components.
Electricity enters the transformer at a high voltage, coming from the generation stage, like a generator. For an 11kV Oil Immersed Power Transformer, the incoming voltage is specifically 11,000 volts.
As electrical current flows through the primary winding, it generates a magnetic field around it. This magnetic field induces a voltage in the secondary winding through electromagnetic induction.

The induced voltage in the secondary winding can be of a lower or higher voltage, depending on the transformer configuration. Essentially, it changes the incoming voltage to a useable level for distribution.
While the transformation occurs, the insulating oil circulates in the tank. It absorbs the heat generated, keeping temperatures within safe limits. This action also helps prevent moisture build-up, which, if left unchecked, can harm transformer operation.
Industrial Usage: Factories frequently use these transformers to step down voltage from the generators for machinery and operational needs.
Renewable Energy Systems: In wind and solar energy installations, these transformers connect generated power to the grid efficiently.
Commercial Buildings: Shopping malls and offices often employ these transformers to distribute electricity safely for lighting and equipment use.
An 11kV Oil Immersed Power Transformer plays a crucial role in the safe and efficient distribution of electricity. By transforming voltage levels while ensuring reliable cooling and insulation, this type of transformer is integral to various applications, from industrial to commercial.
