Abstract

PURPOSE:To enable to evaluate the corrosion property of an insulating oil for a short period with higher accuracy, by heating an insulating oil sample and a metal sample in an N2 gas atmosphere along with irradiation with a beam of light and activating corrosive sulfur in the oil to permit sulfurizing reaction to be accerelated. CONSTITUTION:A heating medium 2 is heated uniformly on heating by means of a heater 6 and on agitation by means of an agitator 3, and the temperature is detected by a temperature detector 4. Thus by controlling the supply of a current to the heater 6, e.g., said heater 6 is set always to the operating temperature of an oil- immersed electrical device. The heating medium 2 controlled in temperature heats indirectly an insulating oil sample 9 and a metal sample 10 that coexist in an N2 gas atmosphere and further a beam of light from a light source 7 irradiates simultaneously the insulating oil sample 9 to permit the corrosive sulfer component in the oil to be activated and sulfudizing reaction with the metal sample 10 to be accelarated, thereby allowing time needed to reach saturation to be shortened considerably.
