Fan Cooled Transformer Ratings at Levi Rounsevell blog

Fan Cooled Transformer Ratings. Up to 2500 kva, the transformer’s cooling surface (tank and radiators) is air cooled by natural convection. In a large rating transformer, more heat is generated, and the convection circulation of transformer oil is replaced with forced circulation. Cooling fans and oil pumps increase the cooling efficiency of the other cooling. General construction features of general purpose ventilated transformers rated 600 v and below. In this method of cooling the flow of oil is natural convection but to increase the rate of cooling of oil, we. It is important to keep dry. Compared to other transformer cooling methods, the onan cooling method has a lower overall heat dissipation capacity. An example of multiple ratings would be onan/onaf/onaf, where the transformer has a base rating where it is cooled by natural. For transformers above 60 mva rating, the onaf cooling system is inadequate, and the ofaf cooling system is used. Transformer cooling classification is different for dry type and liquid. Onaf stand for oil natural air forced cooling.
