Research on the State Evaluation Method of Voltage Transformers Based on Cloud-Edge Collaboration (CICED 2024)

Voltage transformers are key devices in power systems, and their state evaluation is crucial for grid reliability and safety. This study introduces a state evaluation method using cloud-edge collaboration technology. It examines the impact of high-voltage access on measurement errors, focusing on secondary signal errors in high-voltage environments. Technologies like high-precision AID conversion, voltage-to-frequency conversion, and optical fiber synchronization enable accurate data acquisition and transmission at the high-voltage end. loT data interaction allows on-site and remote server data integration. By using historical calibration data, the method provides a comprehensive state evaluation of voltage transformers, enhancing measurement accuracy and supporting stable grid operation.
