Transformers are a vital element of any
power distribution system. In order to
achieve enhanced operational safety,
transformers are normally installed in
protective enclosures. Using enclosures
with a high protection class, the transformer
is optimally protected against
adverse environmental conditions, such
as dirt, carbon or metal dust, or dampness
and moisture, thus increasing the
lifetime of the transformer. Thanks to a
cooling system newly developed by ABB,
