The aim of the article is to provide the reader with the basic concept of the transformer’s heat utilization where a proposed technical solution anticipates the installation of an additional oil-water heat exchanger (ODWF) in the transformer's cooling system. An increase in the transformer’s cooling capacity lowers the oil temperature and reduces the transformer’s loss of life expectancy. In order to estimate the transformer’s oil temperature profile, as well as the heat power potential at the water side of the ODWF cooler, a numerical investig...
