• Expansion and contraction of oil cause breathing action. The silica gel dehydrating breather absorbs any humidity in the air breathed. An oil seal in the air intake prevents external moisture being absorbed when no breathing occurs. • The breather container is filled with silica gel crystals. It is arranged such that the air breathed must pass through it. The desiccant contains blue and white crystals. When the silica gel is fully active, the blue crystals will have a deep blue colour and changes to pink as it absorbs moisture. When saturated with moisture, the silicagel contained should be replaced. The gel removed from the breather may be arranged for regeneration and preserved for future use. • The silicagel crystals are bright orange in case of non-carcinogenic silicagel breather and turns purple/bluish when exposed to moisture. • The size of the breather is chosen such that it can operate effectively over a period of six months approximately. The factors, which influence the selection of size of the silica gel breather required for a particular transformer, depend on many factors like, the oil quantity in the transformer, the TBI AF/IMS001/R3 Installation, Commissioning, Operation & Maintenance of Transformer 24 | P a g e adsorption capacity of silica gel, the loading pattern and the atmospheric conditions prevailing at site. • The loading pattern and the site conditions are difficult for the transformer manufacturer to assess. Hence, the selection of breather is based on certain assumptions and it is difficult to fix up a time schedule for the regeneration of silica gel. It is advisable to have a periodic inspection (say monthly) of the indicator so that the gel can be regenerated or replaced as soon it is saturated with moisture. • Fill the oil in the oil cup up to the marked level on it
