Abstract :
The states of water dissolved in the liquid dielectric di-octyl-phthalate (DOP) were analyzed using the infrared (IR) absorption spectra of water measured by Fourier-transform IR. The states of water in DOP are shown to be independent of the gas impurities, as well as independent of the stress. The H2O molecules are classified into monomer, dimer and trimer, and the formation is independent of the dissolved gas in DOP. Monomers do not contribute to the conduction whereas the conduction depends on the amount of dimer and trimer
