Understanding the impacts of moisture and thermal ageing on transformer's insulation by dielectric response and molecular weight measurements (2008, methodology): “It was described in [37] that according to Fabre and Pichon [38], IEEE Transactions on Dielectrics and Electrical Insulation Vol.”
Aging of oil-impregnated paper in power transformers (2004, methodology): “It is commonly accepted that when the DP has fallen to about 200, the tensile strength of the paper has dropped to 20% of its original value, and the inter-fiber forces have also diminished [ 9 ].”
Dielectric response of mineral oil impregnated cellulose and the impact of aging (2007, methodology): “The main problem of aging of the cellulose based insulation system in a transformer is reduced tensile strength of the paper resulting in reduced ability to withstand through current fault forces on the winding [3, 4 ].”
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].”
