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.
