What is Effects of Oxygen and Water on Transformer Insulation Aging about?

The document discusses how heat, water, and oxygen accelerate the degradation of cellulose insulation in power transformers. It describes a study that measured the individual and combined effects of these factors on aging, as indicated by changes in the degree of polymerization of paper and concentrations of degradation products in oil. The study found that temperature and water have the strongest effect on aging, with oxygen being about one-third as effective. It also found synergistic effects between temp
