MANUFACTURING METHOD OF COLOR SAMPLE/COLOR DIFFERENCE CRITERIA AND DETERIORATION DIAGNOSIS METHOD FOR OIL-FILLED ELECTRICAL EQUIPMENT USING COLOR DIFFERENCE CRITERIA

摘要

To provide equipment and deterioration diagnosis methods that can easily and quickly perform deterioration diagnosis of oil-filled electrical equipment.SOLUTION: The degree of deterioration of oil-filled electrical equipment is diagnosed, after draining insulation oil from the oil-filled electrical equipment that is subjected to deterioration diagnosis, or after exposing the insulator to the atmosphere such as by lifting the electrical equipment body, by imaging an insulator that constitutes the oil-filled electrical equipment by adjusting the white balance together with the white color reference, and evaluating the average degree of polymerization by comparing the photographed image with the color sample using the color difference criteria.SELECTED DRAWING: Figure 1
