For proper functioning of transformer dehumidification of Silica Gel crystals & removal of dust particles from breathed air is necessary.

Moisture is removed from Silica Gel crystals by heating it inside a ventilated oven at to 150 C, until the color becomes deep blue again.

Dusts particles are filtered by the oil in the oil cup.Pressure value for air passage into the breather are: 0.003 Kg/cm inlet or 0.005 Kg/cm outlet.

Criteria for Selecting Silica Gel Breather :
Keeping in view the above functions of Silica Gel Breather the main criteria for selecting the breather becomes,

• Gel changes color from deep blue to pinkish white as it absorbs moisture. By reheating, the Gel becomes free from moisture & hence transformer always breathe in dry air. Visibility of Gel color is very important to decide when to reheat the Gel.
• Oil in the oil cup allows dust particles of air to settle in the oil. By changing the oil & cleaning the oil cup air becomes free from dust particles. Visibility of oil level & dust particle in the oil cup is very important to decide when to change the oil.
• Transformer should breath from breathing holes (provided in breather) only. If air enters through any other portion of the breather except breathing holes it is called leakage of air.
• Leakage of air will lead to entrance of air with moisture & particles in the transformer, which ultimately may lead to formation of spark, and short circuit in the transformer.
