AbstractPower transformers are the most vital components of power system. Insulation used in power transformers are of insulating fluids and solid insulation system like pressboard, Kraft paper. In this work an effort has been made to investigate the detoriation of solid insulation systems for thermal degradation of transformer oil. The aging degree of solid insulation system is examined through Atomic force Microscope (AFM), Scanning Electron Microscope (SEM) and X-ray diffraction (XRD) techniques.
