Summary

This study reports the results of thermal ageing of paper oil insulation of transformers. Laboratory model transformer windings were thermally aged in mineral oil containing different concentrations of DBDS at 125 ºC for different durations and the variation in results of frequency domain spectroscopy and insulation resistance are discussed. The effect of thermal ageing of paper oil insulation at 125 ºC in presence of both DBDS and Irgamet 39 are also discussed and compared.
