In this paper a time domain diffusion-driven model is presented to investigate the correlation between the distribution of moisture during thermal transients, and the resultant polarization and depolarization current (PDC) measurement, for transformer cellulosic insulation. The oil-impregnated cellulosic insulation is modeled as being multiple layers of paper, with each layer having a different permittivity...
Moisture is one of the most significant parameters that can accelerate ageing in paper/pressboard insulation. In order to understand the impact of moisture and ageing on Frequency Domain Spectroscopy (FDS) measurements, oil impregnated pressboard samples of different moisture contents are prepared and aged at 105??C temperature. FDS measurements on pressboard samples are carried out at different ageing...
