Abstract: The operational status of the core components in a fiber-optic current transformer directly affects the accuracy and reliability of measurement results. Therefore, monitoring the status information of these core components is of significant importance. In the communication system of smart substations, the generic object-oriented substation events (GOOSE) information stream is suitable for monitoring devices with small data volumes. It offers advantages such as high real-time capability and the ability to transmit internal information. This paper is based on the GOOSE information stream and designs an information system for monitoring the internal status of fiber-optic current transformers. The system uses the GOOSE send/receive mechanism to transmit and receive status variables. It deciphers the information stream obtained from a Windows data packet capture tool based on the characteristics of the status variables. It utilizes web frontend development technologies with the Vue framework to design interactive interfaces and conducts frontend-backend integration testing. This system allows real-time acquisition, integration, analysis, and processing of internal status information from fiber-optic current transformers. Furthermore, the system can dynamically display processed status information locally and remotely, enabling mutual sharing of information and collaborative operations. In conclusion, by utilizing GOOSE information streams, efficient monitoring of fiber-optic current transformer status information is achieved, enhancing their reliability and measurement accuracy, thereby providing strong support for the development of the smart grid.
