Abstract :
Dielectric properties have been measured in the frequency range from 10 Hz to 100 kHz for some insulating liquids and the results discussed in terms of the dependence of dissolved water. Dielectric constant “ε s” increases remarkably at low frequency when the amount of water is increased under the condition that water binds with dielectric molecules by hydrogen bonding. The AC conductivity of dielectrics with water increases simultaneously according to ε s. Dissolved water makes dielectric molecules more highly oriented, which increases the conductivity
