Why is silica gel used in breather transformers?

Function of Silica Gel Breather. Most of the power generation companies use silica gel breathers fitted to the conservator of oil filled transformers. The purpose of these silica gel breathers is to absorb the moisture in the air sucked in by the transformer during the breathing process. What is Transformer Breathing? read more

Silica gel is used for the absorption of moisture in a transformer absence of which, the dielectric strength of the transformer oil goes down. The breather is used for the movement of Air out of the conservator tank during oil expansion and into the conservator tank during normal conditions. read more

A silica gel breather is the most commonly used way of filtering air from moisture. Silica gel breather for transformer is connected with conservator tank by means of breathing pipe. Construction of Silica Gel Breather The silica gel breather of transformer is very simple in the aspect of design. read more
