Resumen

The reliability of power transformers is critical for ensuring stable and efficient energy distribution. Traditional transformer maintenance methods often rely on reactive strategies, leading to unexpected failures and costly downtime. This study proposes an advanced health index prediction model using the CatBoost algorithm to enhance predictive maintenance strategies. By leveraging key diagnostic indicators such as dissolved gas analysis (DGA) parameters, oil quality indicators, and electrical properties, the model effectively predicts transformer health status. The research explores various train-test split ratios and hyperparameter tuning to optimize model performance. Results indicate that a 75-25 train-test split yields the best predictive accuracy, with an R² of 0.759 
and the lowest RMSE of 9.089. The findings highlight the effectiveness of CatBoost in handling categorical data, improving model interpretability, and reducing overfitting. This approach enables utilities to make proactive maintenance decisions, minimizing unexpected failures and extending the lifespan of transformers.
