Abstract :
Moisture content influences the dielectric properties of paper oil insulation of power transformers. The Polarization/Depolarization current measurements help to understand the dielectric response and conductivity of paper-oil insulation system. This unique concept facilitates the dissipation factor measurement over a wide frequency range. The results provide information on insulation condition such as moisture content in paper oil insulation in both qualitative and quantitative way. This paper discusses the PDC and FDS characteristics of paper oil insulation containing moisture and copper sulphide which is formed due to sulphur in oil.
