Аннотация: this article deals with the problems of purification of contaminated dielectric liquids by force fields. The necessity of finer cleaning in comparison with the existing methods is revealed and justified, which will reduce the threat of rapid wear of the equipment, premature clogging of filters of the main systems, and in some cases - emergency situations. On the basis of the study, the authors propose a scheme of electric cleaner of dielectric liquids and gases with vibration isolation.
