The factors affecting transformer remnant life estimation are analyzed in view of the transformer testing data.On the basis of the established information for remnant life estimation of power transformer,a formula which reflects transformer's health condition and remnant life is deduced according to the current information.The model is applied to calculate the health index and remnant life of a transformer.Estimation result shows consistency with the practical condition of the transformer.
