IEEE C57.119-2001

Write Recommended Practice for performing Temperature Rise Tests on Power Transformers for the purpose of: A. Determining the Thermal Characteristics of a transformer required to calculate the Thermal Performance of a Transformer loaded at Loads other than name plate rating. B. Verify that a Transformer can be loaded with a specified load profile without exceeding specified Temperature Rises. C. Asses a Transformer performance during loading simulating A LOAD CYCLE including loads in excess of nameplate rating.
