A study of the precipitation mechanism in GK transformer oil
Abstract
The room-temperature IR spectra of fresh, used, and aged under model conditions GK trans-former oil, as well as of its residue, are recorded, interpreted, and compared. Analysis of the data obtained confirms the presence of small amounts of aromatic compounds in these samples and shows that the fraction of aromatic and oxidized compounds in transformer oil increases during exploitation. Based on this, a new precipitation mechanism in transformer oil is proposed.
