The relatively high moisture in oil-paper insulations will accelerate cellulose aging and decrease the dielectric withstand strength
so it is very necessary to measure moisture content.A new moisture content measurement method is introduced in this paper
adopting polarization and depolarization current method and frequency domain spectroscopy method.Application examples are presented and the result proves the method is practical.
