How to monitor intelligent transformer

The monitoring of intelligent transformer mainly depends on the built-in intelligent sensing system. These sensors can collect key operating parameters of transformer in real time, including temperature, oil pressure, voltage, current, load rate, partial discharge and so on. For example, the temperature sensor can monitor the changes of winding and oil temperature, and discover the hidden danger of overheating in time; The partial discharge sensor can capture the weak discharge signal inside the transformer and provide a basis for insulation state evaluation.
　　n addition to data acquisition, intelligent transformer is also equipped with data processing and communication module. After preliminary processing, these modules upload the collected data to the cloud platform or local monitoring system through Ethernet or wireless communication technology (such as 4G/5G) to realize remote monitoring and centralized management. Operation and maintenance personnel can check the transformer operation status at any time through the monitoring platform and receive abnormal alarm information, thus realizing the transformation from "passive maintenance" to "active maintenance".
　　he intelligent transformer monitoring system also introduces big data analysis and artificial intelligence technology. Through deep learning and modeling analysis of historical data, the system can predict the possible failure trend of equipment in the future, make maintenance plans in advance, and avoid sudden power failure accidents. For example, the insulation life prediction model based on artificial intelligence algorithm can help operation and maintenance personnel to evaluate the aging degree of transformers and arrange the replacement cycle reasonably.

In addition, the monitoring function of the smart transformer is also connected with the dispatching system of the smart grid, so that it can automatically adjust the output according to the load change of the grid and realize the efficient utilization of energy. This intelligent regulation not only improves the quality of power supply, but also helps to reduce energy consumption and operating costs.
　　In a word, the intelligent transformer realizes comprehensive, accurate and real-time monitoring of the equipment operation state by integrating various sensing technologies, communication means and intelligent analysis algorithms. It not only improves the operation efficiency and security of power system, but also lays a solid foundation for the development of smart grid in the future. With the continuous progress of technology, intelligent transformers will play an increasingly important role in the power industry.
