Dissolved water in insulating liquid had been regarded as a kind of impurities that deteriorates electrical property. Recently, the state and the behavior of water molecules in liquid were measured by IR method. And it comes to be able to be analyzed where water molecules bond with dielectric molecule and how many molecules gather around polar base, among the alkyl chain. In the case of transformer oil, which almost consists of saturated hydrocarbon, oxidation products gradually increase by aging during the practical use. And oxidation compounds include the polar base such as carbonyl base and ketonic base. When water dissolves in such oil, water molecules interact with those polar base and form water cluster, which can make conductivity increase. In this paper, partially oxide hydrocarbon was mixed in saturated hydrocarbon. And the effect of water cluster around the ketonic base on the conductivity was discussed. As a result, when the ratio of oxide compounds was less than 10%, conductivity didn’t increase with increase of water. But the ratio became over 10%, specific water cluster increase conductivity. It was appeared hat the specific cluster consist of water molecules gather around one ketonic base.
