The state and behavior of the water in insulating liquids, gases and films

The water in insulating materials influences their electrical properties and chemical reaction relating their life time. For example, such influences are the effect on the breakdown voltage in oils, the water tree in XLPE cables, the discharge inception voltage in SF6 gas, et al. These influences caused by the water in the materials are well known, however the “state” or “behavior” of the water in detail has not been understood. Then, we have studied the state and behavior of the water by observing the IR spectrum of the water, because the structure caused by hydrogen bonding is represented on IR spectrum. Our studies have been started for the state of water in dielectric liquid, but now the studies are carried out for the water in some kinds of gases, the insulating paper, at el. In this paper, we explain the way to interpret the IR spectra of water and present the state of water in gases, liquids and polymers
