Breather is used for t/fr.this is a container in which
silicon cristal is packed .it used to provide the dry air
for the t/fr.

Answer / d m fulzele

Breather is use in transfoimer.
Due to continuous change in load conditions, oil in
transfomer comprased or expands. when oil comprased it take
external air in through breather. breather contains silica
gel which is used to absorb the moisture in air and supply
dry air in transformer conservator tank. If moisture
contained air passes in to the tank will mix with oil and
the BDV of oil will be low and hence the life of
transformer.
