ventilated dry-type transformer: A dry-type transformer which is so constructed that the ambient air may circulatethrough its enclosure to cool the transformer core and windings.
nonventilated dry-type transformer: A dry-type transformer which is so constructed as to provide no intentionalcirculation of external air through the transformer, and operating at zero gauge pressure.
sealed dry-type transformer: Self-Cooled. A dry-type self-cooled transformer with a hermetically sealed tank.IEEE C57.94 pdf download.
