Abstract
PURPOSE: To measure the electric resistance and dielectric resistance of an insulating oil at its oxidation deteriorating process accurately by measuring the electric characteristics, dielectric breakdown strength of the insulating oil in an enclosed container having a heater, circulating conduit, etc. using the electrodes and the dielectric breakdown electrode in the container.
CONSTITUTION: An insulating oil 3 is circulated in an enclosed container 20 through a liquid pump 9 and a circulating conduit 8, etc. The dielectric breakdown strength, boundary tension, chromaticity, sludge amount, etc. are measured by sampling the oil 3 through a collecting port 16. On the other hand, the oil 3 in the container 20 is heated to desired temperature by a heater 4, and nitrogen, oxygen, etc. are supplied from a supply port 5 to the container 20. Further, the electric characteristics, dielectric breakdown strength, etc. of the oil 3 are measured by the electrode 10 and the dielectric breakdown electrodes 12, 13 dipped in the oil 3 of the container 20 to thus measure not only the oxidation and the sludge amount but the electric resistance and dielectric tangent of the oil at its oxidation process so as to test the stability of the stable insulating oil.
