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.
