Sažetak
In the piping between the tank of a 40 MVA transformer, originally designed for ONAN/ONAF cooling combination, and its bank of radiators, a propeller oil pump was installed. Characteristic temperature rises were measured before and after installation of the pump. The results were applied to the development of a new algorithm for calculation of windings and oil steady-state temperature rises of ONAN/ONAF/OFAF transformers. The mathematical model is briefly described in the paper, and the basic thermal characteristics of transformers with this combination of cooling types are described. Installation of the oil pump can make transformer cooling more efficient provided that certain conditions are satisfied.
