Abstract :
An attempt is made to describe simply and clearly the basis of the temperature rating of oil-immersed transformers and the relations between the temperatures measured in service, the maximum safe output rating, and the national standard ratings. A description is given of an instrument for indicating the safe output rating of a transformer in service under any conditions of short time or continuous loading.
