- Space charge behavior in multi-layer oil-paper insulation under different DC voltages and temperatures (2010, background): “The power transformer insulating paper is made up of cellulose (89%~90%), hemicellulose (6%~8%) and lignin (3%~4%) [ 13-14 ].”
- Understanding the impacts of moisture and thermal ageing on transformer's insulation by dielectric response and molecular weight measurements (2008, methodology): “It was pointed out in [ 37 ] that in such cases, there may be an opposed interaction between oxygen and water, which may result in a reduction in ageing rate at low water levels and low temperatures when the oxygen concentration in the oil increases due to ingress of air.”
- Dielectric response of mineral oil impregnated cellulose and the impact of aging (2007, background): “The higher the temperature, moisture content, content of water soluble acids (particularly together with moisture) or oxygen content is, the faster the aging proceeds [ 1-3 ].”
- Aging of oil-impregnated paper in power transformers (2004, result): “We find that oxygen increases aging by a factor of about two, which also agrees with what Emsley later found [18].”
