Since the conditions such as short circuit and serious overheating. Finally, merging of multi-source heterogeneous parameters can reduce combined with the case the residual life and the fault the error caused by single parameter and increase the accuracy probability of power transformer are analyzed to validate the of longevity prediction model, the proposed model collects effectiveness of the proposed model. Results of this research characteristic parameters, which can be used to assess the are available for reference to the condition based maintenance longevity information in the present. Based on hierarchical of power transformer and increasing its service life. architecture the q
