Abstract The temperature of transformer oil is a critical indicator reflecting its internal insulation status. Traditional monitoring methods suffer from issues such as high promotion costs and insufficient real-time capabilities. This paper develops an oil temperature monitoring and early warnign system based on deep learning technology, employing a gated recurrent unit (GRU) network integrated with an attention mechanism to model and dynamically forecast oil temperature data. Tests on a measured dataset from a substation demonstrate that the Attention-GRU model outperforms traditional models across multiple metrics, including mean absolute error and the coefficient of determination. Deployed on a server, the system features a user-friendly human-computer interaction interface, enabling real-time monitoring of oil temperature values, prediction results, and abnormal warnings. This enhances operational efficiency and equipment safety.
