Breather plays a vital role in the power transformers.
When the transformer gets loaded,the cooling oil in the
transformer tank gets heated and due to which the volume of
the oil in the tank expands as per its property with
respect to the load and duly gains its original when it
attains cool.
Hence,to perform such cushioning action,the transformer
requires a way to push & pull the air.Without which the
tranformer would burst drastically.
While performing the action,normally the water content in
the moiture enters into the tank,which inturn leads to
short circuit.Hence to avoid ,a silica gel / crystal
chamber fitted just adjacent to the breather,which captures
the water content while air intake thro' breather.
