Abstract: Various embodiments of the disclosure include a system having: a computing device configured to monitor a sealing oil from a dynamoelectric machine by performing actions including: establish a baseline flow rate for the sealing oil through the dynamoelectric machine for designed operating conditions; calculate a plurality of average flow rates for the sealing oil through the dynamoelectric machine from a set of measured flow rates in each of a plurality of successive designated periods; provide an alert suggesting action in response to at least one of the average flow rates deviating from a threshold flow rate, the threshold flow rate derived from the baseline flow rate to indicate a fault in the sealing oil; and calculate an expected sealing life for the sealing oil based upon a pattern in the plurality of average flow rates for the plurality of successive designated periods.

Abstract: Various embodiments of the invention include a system having: at least one computing device at least one computing device configured to monitor a lubrication oil by performing actions including: determining an initial ideal remaining life for the lubrication oil; determining a temperature-based remaining life for the lubrication oil based upon a temperature measurement of the lubrication oil; calculating a contamination factor of the lubrication oil based upon a non-particle count sample of the lubrication oil; determining an updated ideal life remaining for the lubrication oil based upon the contamination factor, the initial ideal remaining life, and the temperature-based remaining life; and determining an actual life remaining for the lubrication oil based upon the updated ideal life remaining and an actual life lost for the lubrication oil.
