Abstract: This paper represent the experimental investigation on power transformer insulation based on accelerated electrical & thermal stresses. In this paper, effect of accelerated thermal and electrical stresses on dissolved gas analysis has been experimentally investigated. A new terminology accelerated electrical aging factor (AEAF) & accelerated thermal aging factor (ATAF) is introduced which is mathematically correlated with dissolved gas analysis (DGA). DGA were determined experimentally for fresh and stressed oil samples.
Keywords: Power Transformer, insulation oil, dissolved gas analysis (DGA), accelerated thermal aging factor (ATAF), accelerated electrical aging factor (AEAF).
