When to use air forced cooling in a transformer?
The fans are automatically controlled, that is when the temperature of the transformer core goes beyond the safe limit than all the fans are switched ON. Air forced cooling method provides better performance than natural air cooling, but additional cost is associated for the fans. This cooling system is used in oil immersed type transformers.
Why does a dry type transformer need to be cooled?
As dirt accumulates on cooling surfaces, it becomes more and more difficult for air around the transformer to remove heat. As a result, over time, the transformer temperature slowly rises unnoticed, reducing service life. Cooling classes of dry type transformers are covered by ANSI/IEEE standard C57.12.01.

How does a self cooled transformer get its rating?
The self cooled rating (A) is obtained by Natural Circulation of air over the tank and cooling surfaces. Liquid-immersed, forced liquid-cooled with forced air-cooled. This transformer normally has only one rating. The transformer is cooled by pumping oil (forced oil) through a radiator normally attached to the outside of the tank.
