What is the purpose of oil-filled Eaton transformers in power applications?

The purpose of oil-filled Eaton transformers in power applications is to provide electrical insulation and cooling. The transformer oil serves as a dielectric medium, preventing electrical discharges and enhancing safety. Additionally, the oil dissipates heat generated during operation, maintaining optimal temperatures within the transformer. This dual function of insulation and cooling is crucial for the reliable performance and longevity of Eaton transformers in power applications.
