Abstract :
Increase of temperature rise and hot spot values affects dramatically transformer aging and life expectancy. The present article deals with optimum designs of ONAN transformer cooling system by means of advanced numerical thermal field and computational fluid dynamics techniques. Novel tank designs are examined in conjunction with other crucial parameters, as the number and location of the winding cooling ducts, so as to define the best optimum geometry that ensures maximum efficiency of the transformer cooling system performance.
