| The failure or malfunction of many
transformers or similar equipment can be directly attributed to
the lack of proper control of the level of water vapor entering
the equipment. It
is essential, therefore, that a very low level of humidity is maintained
in the airspace of the conservator tank to avoid deterioration
in the insulating properties of the cooling medium.
Transformer Desiccant Breathers provide an economic and efficient means
of controlling the level of moisture entering equipment during
the change in volume of the cooling medium and/or airspace caused
by temperature gradients. All Transformer Desiccant Breathers (except Re-Actran) are filled with self-indicating silica
gel. This desiccant is blue when active and turns pink when
saturated. This allows a visible assessment of the condition
of the desiccant. Various sizes and types of packs of this
desiccant are available for recharging the desiccant containers. |
