Why Oil is Required for Transformers

Image
  The transformer oil provides things that help maintain the transformer's efficiency and durability; one is insulation and another is cooling. It is important for electrical as well as thermal performance of transformers. A highly refined mineral oil is used as an insulator between transformer’s windings. This insulator prevents electrical breakdown and transformer damage. In this blog, let us explore four main functions of this oil in a solar transformer or any other type of transformer for that matter. Four Main Functions of the Transformer Oil Heat Transfer When the transformer is working, it produces heat. This heat comes from the electrical load and the surrounding temperature. Let us say the environment is hot; this will add more heat, and the transformer will run even hotter. To disperse this heat from the core and coil, the transformer requires oil. This oil prevents temperatures from rising to damaging levels. Dielectric Strength Both the paper and oil inside a transform...
