Abstract
PURPOSE: To obtain a gauge which expresses adequately deterioration stages right before replacement from new oil, by estimating the gauge from the kinematic viscosity and interfacial tension of turbine oil.
CONSTITUTION: In accordance with the kinematic viscosity and interfacial tension (y) of turbine oil at 50°C, turbine-oil deterioration control gauge Z based upon formula I is determined. As a result, curves 1W3 of elapse to gauge Z corresponding to a use state vary linearly and the deterioration of the turbine oil can adequately be appreciated from its initial use stage until its last deterioration stage needed for replacement, and the last deterioration stage can also be predicted.
