Abstract :
This paper presents results of Frequency Domain Spectroscopy (FDS) and Polarization/Depolarization current (PDC) for understanding the combined effects of copper corrosion and moisture content in paper oil insulation of transformers. This method is not fully exploited and documented for applications to field studies. Hence an attempt is made to understand the effects of copper corrosion and moisture using FDS/PDC. Use of other methods for understanding of copper corrosion phenomena is also discussed.
