Power cut-off system and method
By installing an adapter-type circuit breaker system between the electricity meter and the meter socket, and using Rogowski coils to sense current and a processor to control relays to switch power supplies, the complex and costly switching between the mains and backup power in residential buildings is solved, achieving safe, automatic and dynamic power management.

AI Technical Summary
In residential buildings, existing technologies struggle to effectively manage and safely switch power supplies between the main grid and backup power sources, especially to prevent backup power from feeding back into the grid during grid failures. Furthermore, existing systems are complex to install and costly.
A circuit breaker system was designed. By installing an adapter-type circuit breaker system between the electricity meter and the meter socket, the system utilizes Rogowski coils to induce current and a processor to control relays to switch power supplies, thereby achieving automatic and dynamic switching between the mains and backup power sources and ensuring safe and efficient power distribution.
It enables automatic switching to backup power in the event of a grid failure, ensuring safety, simplifying the installation process, reducing costs, and providing real-time monitoring of grid status and dynamic power management.
