In transformer design and operation, the choice of cooling method is a critical factor\u2014not only does it influence equipment lifespan and reliability, but it also significantly affects operating efficiency. This article explores howdifferent cooling methods such as ONAN, ONAF, and OFAF\u00a0impact transformer performance, analyzes the underlying thermodynamic principles, and provides data to help electrical engineers and procurement decision-makers make more informed choices. Globally, with rising energy efficiency standards (such as IEC 60076, IEEE C57.12.00, etc.), understanding the relationship between cooling methods and transformer efficiency transformer efficiency has become increasingly important."}
