Abstract
This paper gives a summary of the requirements and calculating methods for the maximum insulated conductor temperatures (usually referred to as hottest-spot temperature or hot spot temperature) in oil-immersed transformers. Laboratory experiments were performed on a 5 kV, 100 kVA transformer using thermocouples during the short circuit heat run tests, and the measurements from the tests are employed to compare some of the methods mentioned in the paper.
