ABSTRACT:
A transformer having a forced air cooling system is disclosed. The transformer includes an insulating oil which is forcibly moved in the transformer and an insulating sheet which is partially covered with particles, fibers or other forms of an inorganic material for producing a static charge of opposite polarity to the charge produced by the base material of the insulating sheet caused by relative motion due to forced flow of the insulating oil.
