Introduction to Oil Immersed Transformer
An oil – immersed transformer is a type of transformer where the core and windings are immersed in insulating oil. The insulating oil serves multiple crucial functions. Firstly, it provides electrical insulation between the different components of the transformer, preventing short – circuits. Secondly, it acts as a coolant, carrying away the heat generated during the operation of the transformer. This heat – dissipation function is essential to ensure the long – term and stable operation of the transformer. Oil – immersed transformers are widely used in power systems, industrial facilities, and commercial buildings due to their high reliability and relatively low cost. Oil Immersed Transformer
