Low Voltage Distribution Network Data Sensing and Fault Analysis System

This paper introduces a sophisticated system designed for the sensing and analysis of faults within low-voltage distribution networks, specifically tailored for the 0.4kV infrastructure. Anchored by the Smart Transformer Terminal Unit (STTU) framework, the system adeptly meets the operational and inspection management demands while upholding stringent information security protocols. The system is adept at capturing operational parameters and performing real-time fault diagnosis on-site for the facilities it monitors. It ensures that the data gathered is securely sent to the power grid company's Internet of Things (IoT) management platform, leveraging a robust 4G APN communication network to maintain data integrity and confidentiality. Through its practical engineering applications, the system has proven instrumental in the efficient monitoring of low-voltage distribution operations and in the precise analysis of power outage causes.
