What Does ONAN Transformer Mean? ONAN transformer (or ONAN cooling) is the simplest transformer cooling method at which the nature oil and nature air flow are used in cooling oil immersed transformers. No fans or oil pumps are used in this method. ONAN transformer cooling stands for the the first letters of Oil Natural Air Natural.

What is the difference between onaf and OFAF? 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.
What is onaf cooling? ONAF, Oil Natural Air Forced, transformer cooling represents the cooling method of transformers using forced air flow with fans, and natural transformer oil flow, i.e no pumps, to enhance and accelerate the heat dissipation from the transformer. ONAF is a cooling method for both oil immersed and dry type transformers.
What is the difference between onaf and transformer cooling? This is a simple transformer cooling method, it has no fans for air and has no pumps for the oil. While ONAF stands for Oil Natural Air Forced, we use cooling fans to increase the cooling efficiency and to speed up the heat dissipation. This means that the transformer cooling has fans for air.
