What is the purpose of immersing the transformer in an oil tank?

The purpose of immersing the transformer in an oil tank is to provide effective cooling and insulation. Transformer oil absorbs heat generated during operation, maintaining optimal temperature levels and preventing overheating. Additionally, the oil acts as an insulating medium, preventing electrical discharges and enhancing the transformer’s reliability and safety. This immersion in an oil tank is crucial for the efficient performance of power transformers.
