These designations refer to the means by which heat is removed from the Transformer. ``AA`` refers to Ambient Air. This is the natural convection cooling of dry Tranformers. ``AA/FA`` refers to a Transformer that under lower loading conditions uses natural convection for cooling, but under heavier loading conditions, Forced Air ``FA``, typically accomplished the addition of motor driven fans, increases the rate at which heat is removed from the Transformer.
