Use of breather:
Insulating oils require protection from humidity. The highest degree of de-humidification ensures better die-electric values.
Transformers use insulating oils to keep the instrument temperature under control along with other electrical properties.
The quantity of oil filled into a transformer is constantly expanding and contracting due to volumetric changes brought in by
thermal heating and cooling during loading and no load condition. The expansion in a container expels air outside and
contraction rushes air inside. Silicagel is a chemical having unique property of absorbing moisture from air.
A breather filled with silicagel is used on each transformer to absorb entire moisture from the air entering
the conservator during breathing or contraction period.
