Right Answer is:

Absorb moisture of air during breathing


Transformer oil should not be exposed directly to the atmosphere because it may absorb moisture and dust from the environment and may lose its electrical properties in a very short time. To avoid this problem a breather is provided on the top of the conservator.

Breather is the heart of the transformer, which is similar to the human heart. The breather transports fresh air in and out of the transformer. This component is required to maintain the cooling-medium level in the conservator.

Breather mainly consists of a silica gel. The silica gel absorbs the moisture content of air so that oil contamination can be prevented. The silica gel which is blue in color turns pink when it absorbs moisture fully. it is replaced periodically as routine maintenance.
