After along time a posting this Video that Shows a150MVA Transformer Breathing Out Process:-

When load on transformer increases or when the transformer under full load, the insulating oil of the transformer gets heated up, expands and gets expel out in to the conservator tank present at the top of the power transformer and subsequently pushes the dry air out of the conservator tank through the silica gel breather. This process is called "Breathing Out"of the transformer.

When the oil cools down, air from the atmosphere is drawn in to the transformer. This is called "Breathing In"of the transformer.

It's happen simply because of a "LOOSE CONNECTION" ,so during preventive maintenance works one should take of this..
