Zusammenfassung: | Recently, remarkable progress has been made in the application of machine learning techniques (e.g., neural networks) to transformer fault diagnosis. However, the diagnostic processes employed by these techniques often suffer from a lack of interpretability. To address this limitation, this letter proposes a novel glass-box model that integrates interpretability with high accuracy for transformer fault diagnosis. In particular, the model captures the non-linear relationship between dissolved gases and fault types using shape functions, while also modeling the correlations between dissolved gases through interaction terms. Simulation results demonstrate that the performance of the proposed glass-box model surpasses those of benchmark models. Furthermore, the model offers both global and instance-specific perspectives for the interpretation of diagnostic processes. The combination of high accuracy and interpretability makes the proposed glass-box model an attractive option for reliable transformer fault diagnosis. |
