According to exist problem of servomechanism health condition assessment because of complicated measurement data, a method that based on grey target theory is proposed. By combining the principal component analysis (PCA) and correlation analysis to filter index and determine index weight, then target correlation was obtained by weighting the coefficient of correlation between measurement sequence and standard model that determined by required figure and measurement data, at last, health condition of servomechanism was assessed by matching health condition degree. Experiment shows that this method with clear procedure can exactly evaluate the servomechanism health condition.

According to the transformer testing information, the factors affecting of transformer remnant life assessment were analyzed. The formula which reflects the transformer health condition and remnant life is deduced and established according to the current information. The model thus is used in the health condition assessment and calculation of the remnant life for transformers. The results show that the process is consistent with the practical situation.
