Abstract
A transformer (26) is monitored by a dissolved gas monitoring device (28). A method (36) in the form of executable code instructs a processor (34) to analyze a condition of the transformer (26). The method includes receiving (90), from the monitoring device (28), data elements (60) in the form of values (70) of dissolved gases (72) associated with operation of transformer (26) during a period of time. Periodic characteristics responsive to the operation of the transformer (26) are identified (92) from the data elements (60). The periodic characteristics may include a daily, semi-annual, and/or annual fluctuation of gas generation in response to transformer loading. A gas generation rate trend (112) is distinguished from the periodic characteristics, the condition of the transformer (26) is determined and its future condition may be predicted in response to the trend (112). The condition is presented to a user (58).
