The lack of proper moisture control and humidity within the equipment is the cause of most malfunctions or failures of transformers or equipment. Therefore, it is vital to maintain a low level of moisture within the space in the conservator tank’s top. The low moisture content prevents the deterioration of the cooling medium’s insulation properties. Transformer Breathers offer an efficient and economical way to control moisture entry and maintain certain humidity levels within the storage tank or transformer equipment.

Transformer Breathers indicate desiccant; usually, Silica Gel is filled inside the transformer. They absorb moisture from the air as it passes through the breather and ensure that only dry air enters. Once fully saturated with moisture, the Silica Gel changes colour from blue to pink, indicating the need for replacement.
