Abstract

PURPOSE: To realize the measurement for various types of characteristics during and after heating by providing the oxygen gas supply opening, the heater and the oil draw-out opening each to the sealed container which is capable of storing the sample of a desired amount.
CONSTITUTION: The inner wall of metal container 1 possessing opening 1a containing the flange at one end receives the surface treatment via the resin or the glass to form sealed container 20. Insulating oil 4 is stored into container 20 in a desired amount. Heater 5 is provided at the bottom part of container 1 to heat up oil 4. In addition, the following openings are provided: air absorption opening 6 to link the space between the surface of oil 4 and cover 2 to the outside of container 20; gas supply opening 8 to supply the oxygen gas into oil 4; oil supply opening 10 to supply oil 4; and oil draw-out opening to draw out oil 4 each. Thus, the measurement is possible during and after heating for various types of characteristics including the full oxidation, the interfacial tension, the chromaticity, the insulation breakdown intensity and others of the insulating oil.
