Abstract

Efects of overloading on the life of oilimmersed self-cooled power transformers are discussed in this paper. Experience has shown that under average loads and ambient temperatures, a transformer rated for a temperature rise of 55 degrees C, has a very long life, and can be overloaded considerably for short periods with little loss in life.
