Breathing Process of Transformer :
Breathing is the process where the transformer Breather-In or Breather our the air from its body due to thermal contraction & expansion of oil mass. When the transformer is loaded or unloaded, the oil temperature inside the transformer tank rises or falls accordingly the air pressure inside the tank changes by either breathing in or breathing out the air. This phenomenon is called "Breathing" of the transformer. Now, the air which is being breathed in contains either dust particles and/or humidity that change the dielectric strength of the oil. For proper functioning of transformer, it is absolutely necessary that dielectric strength of transformer oil remains unimpaired. Hence, it is necessary that, the air entering into the transformer is free from moisture & dust particles.

Function of Silica Gel Breather :
The sole function of Silica Gel Breather is to dehydrate (remove moisture) the air & to remove dust particles of the air breathed in by the transformer.

Operation & Working of Silica Gel Breather :
Silica Gel (Air dehydrating) breathers are transparent hollow cylinder tubes which contain chemically pure silicium salt (Silica Gel) with cobalt indicator. This grade of Silica Gel is called as âindicating gradeâ of Silica Gel.

The indicating grade of Silica Gel, which is filled in the breather, is hard blue crystals, which has considerable absorption power for moisture. Silica Gel absorbs moisture signaling the saturation degree by changing color as follows.

  • Deep Blue Silica Gel completely dry
  • Light Blue Silica Gel partly humid. (Absorbed water for about 15% of its weight)
  • Pink Silica Gel saturated with moisture. (Absorbed water for about 30 - 40% of its weight)

 

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.

The Blue Silica Gel (Indicating Type Desiccant Silica Gel) is a semi-transparent glassy substance, containing an indicator as Cobalt Chloride a heavy metal salt. The Granules or beads are dark blue in color when they are free from moisture. As the graduals take up moisture, they turn to light blue gradually, When Dark Blue Silica Gels color of crystal turns from blue to pink, or color less it has absorbed approximately more than 8 % percent of its weight in water making it an easy visual indicator to see whether gel has become saturated with water. It shows whether the gel needs to be replaced or regenerated. The indicating silica gel will still adsorb up to 40% of its weight in water vapor just like the non-indicating. In fact, it is mainly used as indicator for the extent of dehumidification and moisture absorption in sealed vessel and Silica Gel Breather Industry & Transformer Industry. We have an illustrious reputation of delivering high quality Blue Silica Gel.

This phenomenon is called "Breathing" of the transformer. Now, the air which is being breathed in contains either dust particles and/or humidity that change the dielectric strength of the oil. For proper functioning of transformer, it is absolutely necessary that dielectric strength of transformer oil remains unimpaired. Hence, it is necessary that, the air entering into the transformer is free from moisture & dust particles.

Function of Silica Gel Breather :
The sole function of Silica Gel Breather is to dehydrate (remove moisture) the air & to remove dust particles of the air breathed in by the transformer.

Operation & Working of Silica Gel Breather :
Silica Gel (Air dehydrating) breathers are transparent hollow cylinder tubes which contain chemically pure silicium salt (Silica Gel) with cobalt indicator. This grade of Silica Gel is called as indicating grade of Silica Gel.

The indicating grade of Silica Gel, which is filled in the breather, is hard blue crystals, which has considerable absorption power for moisture. Silica Gel absorbs moisture signaling the saturation degree by changing color as follows.
Deep Blue Silica Gel completely dryLight Blue Silica Gel partly humid. (Absorbed water for about 15% of its weight)Pink Silica Gel saturated with moisture. (Absorbed water for about 30 - 40% of its weight)
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.
