Transformer dehydrating breathers are being used
for liquid immersed transformers in order to protect the insulating
liquid and prevent the harmful moisture absorption from ambient
air, which occurs when the load on the transformer fluctuates.The
transformer dehydrating breather removes practically all moisture
from the air that flows through it into the conservator when the
transformer is cooling down. This largely prevents any reduction of
the dielectric strength and the formation of condensation in the
expansion tank. Thus, the dehydrating breathers increases the
operational safety of transformers.
