Abstract
A system includes a power transformer diagnosis and prognosis device having memory circuitry storing a plurality of models. Each of the plurality of models comprises correlations between potential combinations of operational and non-operational power transformer data and potential conditions of one or more subsystems of a power transformer and include a physics-based model and an empirical model. The system includes communication circuitry configured to receive a particular combination of operational and non-operational power transformer data related the power transformer. The system includes processing circuitry configured to provide the particular combination of operational and non-operational power transformer data as inputs to the plurality of models, determine a diagnosis for the power transformer from outputs of the plurality of models, determine a prognosis for the power transformer from the outputs of the plurality of models, and display the diagnosis and the prognosis for the power transformer on a display device.
