    摘要： The present invention relates to an electric insulating oil inspection method for determining whether or not an inhibitor-consuming substance is present in an electric insulating oil. The inhibitor-consuming substance is such a substance that causes to decrease over time a concentration of an inhibitor which is added to the electric insulating oil to inhibit copper sulfide from being generated on an insulating paper immersed in the electric insulating oil. The electric insulting oil inspection method includes steps of: preserving the electric insulating oil at a predetermined condition, measuring a concentration of the inhibitor, and determining that the inhibitor-consuming substance is present upon condition that a decrement of the concentration of the inhibitor relative to an initial concentration of the inhibitor becomes not less than a specified amount within a predetermined period.

    摘要： A dehumidifier for removing moisture from a gas containing moisture comprises a first electrode which is in contact with a gas containing moisture on a first surface thereof and, when a positive voltage is applied thereto, which produces protons from said moisture, a proton conductive solid having first and second portions which is connected to a second surface of the first electrode at the first portion and allows the protons to pass therethrough, and a second electrode which is connected to the second portion of the proton conductive solid on a first surface thereof and in contact with air on a second surface thereof. In a preferred embodiment, the first electrode, the proton conductive solid, and the second electrode are formed as a laminate. When a negative voltage is applied between the first and second electrodes, hydrogen or water is produced from the protons passed through the proton conductive solid.
