Transformers are often cooled by?

Transformers are often cooled by the use of forced cooling with fans. This method is effective because it enhances heat dissipation from the transformer. In practice, transformers can generate significant amounts of heat during operation, and maintaining an optimal operating temperature is critical for their efficiency and longevity. Fans help circulate air around the transformer, increasing the airflow and allowing for more heat to be carried away from the unit.

While other cooling methods exist, such as immersion in oil or water, the option of forced cooling with fans is a common and practical method employed in many commercial applications due to its simplicity and effectiveness in maintaining safe operating temperatures. This makes it a widely accepted cooling solution in the field of electrical engineering.
