For plant maintenance in the electric power industry, the method is shifted from Time Based Maintenance(TBM) to Condition Based Maintenance(CBM). CBM is carried out appropriately after continuously evaluating the condition of the equipment and making a scientific and rational judgment. As a result, an extension of regular inspection cycle and reduction of maintenance costs are investigated in the industry by optimizing the maintenance. Lubricating oil diagnosis, which is one of the diagnostic techniques of CBM, is said to be highly sensitive to failures. On the other hand, it has been difficult to apply to online monitoring. Therefore, we developed a device that distinguishes particles in oil from other particles, and found a useful index for wear evaluation by monitoring the ratio of time change in each particle size range using a contamination classification.
