A transformer that has natural convection cooling as a base rating and an elevated rating when fans were added later, would be designated as ONAN/ONAF. High fire point fluids use the designation of K for fluid type. Thus a naturally cooled high fire point fluid would be KNAN and the same unit.

For transformer above 60 MVA rating, ONAF cooling system is not adequate and OFAF cooling system is used. In large rating transformer, more heat is generated, and convection circulation of transformer oil is replaced with forced circulation. The oil pump is fitted in OFAF types of colling system, the pump forces the oil to circulate and the heat transferred to the radiator is radiated in the. This type of cooling is called ONAF (Oil Natural Air Forced). 3) Further to provide more efficient cooling, large transformers are fitted with pumps which pump the oil between radiator and transformer tank. This type of cooling is called OFAF (Oil Forced Air Forced). In dry type transformer, there is no oil so entire heat is rejected in air ONAF means Oil Natural Air Forced (The oil will be circulated without any forced measure but the air will be blown through fans). This increase the capacity of power transformer by 33% of the base capacity. OFAF means Oil Forced Air Forced (The oil and air will both be circulated through fans). This will increase the capacity of power. While the ONAF transformer power can be increased to be up to 3250 KVA depending on the number of cooling fans. Which One is Better ONAN or ONAF? For simple applications where the load is fixed and small, then only ONAN cooling is the best choice. Sometimes the application needs one transformer with more than one power rating. In my working location transformers with 3 or 4 power rating. ONAF Cooling of Transformer. Heat dissipation can obviously be increased, if dissipating surface is increased but it can be make further faster by applying forced air flow on that dissipating surface. Fans blowing air on cooling surface is employed. Forced air takes away the heat from the surface of radiator and provides better cooling than natural air. The full form of ONAF is Oil Natural.

KNAN/KNAF transformers uses insulating non-mineral oil that has higher fire point (>300 0 C) compared to regular mineral oils (Symbol starts with 'O') used on typical oil filled transformers classified as ONAN/ONAF etc. Non-Mineral oil also increases insulation life of transformer, is more environmentally friendly, is non-toxic, less flammable Da die Wärmeabstrahlungsrate beim ONAF-Transformator-Kühlverfahren schneller und höher ist als beim ONAN-Kühlsystem, können elektrische Transformatoren stärker belastet werden, ohne die zulässigen Temperaturgrenzen zu überschreiten. OFAF Kühlung des Transformators. In Öl Zwangsluft natürlich Kühlsystem des TransformatorsDie Wärmeabfuhr wird durch die Verwendung von Gebläseluft.

The transformer has an ONAN rating at 55C rise and an ONAN rating at 65C rise, as well as an ONAF rating at each temperature rise. You would use the 55C ratings if you want to extend the life of the transformer, knowing that it can be operated at the 65C ratings at the expense of life expectancy Transformer Consulting Services Inc. • (ANSI) IEEE Std C57.12.00-2010, standard general requirements for liquid-immersed distribution, power and regulation transformers • ANSI C57.12.10-2010, safety requirements 230 kV and below 833/958 through 8,333/10,417 KVA, single-phase, and 750/862 throug KNAN, KNAF,ONAN, ONAF First letter - main cooling medium (in contact with the windings) O = mineral or synthetic. oil, flash point < 3000C K = do with Flash point > 3000C L = do with unmeasurable flash point Second: Circulation method of media 1 F = Forced, N = natural D= Forced, Through a cooler Third - External Cooling media A= Air, W= Water Fourth- Circulation of (3) F= Forced, N= natural

  1. What is ONAN, ONAF, OFAF, OFAN IN transformers ? ONAN:- onan is oil natural air natural. For capacity greater than 50 KVA radiators are used for cooling purpose it is in the pipe or tube shape. With the help of radiator the surface area of tramsformer is increased and transformer cooling will be better. When transformer oil heated goes to radiator and returned to tank after cooled heat is.
  2. An example of multiple ratings would be ONAN/ONAF/ONAF, where the transformer has a base rating where it is cooled by natural convection and two supplemental ratings where groups of fans are turned on to provide additional cooling so that the transformer will be capable of supplying additional kVA. This rating would have been designated OA/FA/FA per past standards. SOURCE: Electric Power.
  3. Transformer windings and core are immersed in some type of oil and are self-cooled by natural circulation of air around the outside enclosure. Fins or radiators may be attached to the enclosure to aid in cooling. ONAN/ONAF (OA/FA) Liquid-immersed, self-cooled/forced air-cooled. Same as OA, with the addition of fans.

Transformer rating = 100 kV. Primary voltage or H.V.= 11 kV Primary current= 5.25 A. Secondary voltage or L.V.= 415 volts Secondary current= 139 A (It must be noted that a name plate have many more parameters like phase rotation, tap positions with voltage etc.) Now, if we calculate the rating by using first two equations, we get. The transformers can be designed for any applicable cooling system following the requirements of the end user. The most used cooling systems for power transformers are ONAN and ONAF.
