Method for measuring insulating oil amount, method for measuring polychlorinated biphenyl content, and method for determining detoxification of polychlorinated biphenyls

摘要

PROBLEM TO BE SOLVED: To provide an insulation oil amount measuring method capable of simply measuring the insulation oil amount containing polychlorinated biphenyl adhering to a wide range.SOLUTION: An insulation oil amount measuring method of measuring the insulation oil amount containing polychlorinated biphenyl includes: an irradiation process of irradiating a measurement region with an ultraviolet ray; an image processing process of image-processing the fluorescence generated from the insulation oil due to the irradiation to acquire a fluorescence image; and a calculation process of calculating the insulation oil amount on the basis of the fluorescence intensity of the fluorescence image. In the irradiation process, preferably, light of a wavelength higher than 300 nm in the ultraviolet ray is blocked using a first optical filter.SELECTED DRAWING: None
