Dehydrating breathers are used to prevent the normal moisture in the air from coming in contact with the oil in electrical equipment. They are frequently used on the oil compartment of a load tap changer or on the air side of a power transformer conservator.
The breather contains silica gel which has the ability to scrub the moisture from the air as it passes through the breather. Some breathers are designed for sealed tank transformers and breathe only at preset pressure levels. The dehydrating breathers are filled with Silicage1 that can absorb 20 percent of its own weight in moisture. The breathers are also provided with an oil trap preventing continuous contact between the moist air and the Silicage1, allowing longer life of the Silicage1 and lower maintenance.
Dehydrating breathers are rated by the amount of oil that the breather can protect - the smallest breather can protect an oil volume of 300 gallons - the largest breather can protect an oil volume of 9600 gallons. Multiple breathers can be applied to the same tank or conservator to protect larger volumes. The smallest breather contains about one-half pound of silica gel and the largest breather contains about 18 pounds of silica gel. Why ABB?
