ABSTRACT:
Disclosed is a method of reducing the charging tendency in a flowing non-aqueous liquid which has a dielectric constant of less than about 50, by passing the liquid through an ion exchange resin charged with a weakly polar active group. Also disclosed is a combination of a transformer cooled by flowing organic insulating liquid and an anionic ion exchange resin and means for passing the liquid through the resin.
