Smart Measurement Switch
The smart measurement switch monitors in real time distribution line voltage, current, power, and has advanced applications such as edge management, topology identification and power consumption analysis, with basic features of low-voltage distribution line connection, breaking and short-circuit overload protection. It is developed based on traditional low-voltage switches, high-precision current sensors and measurement units. The product provides good support for digital IOT of distribution network. The product complies with the "Smart Energy Measurement Switch Technical Specification-2021". Its measurement unit is module-based and separated from the switch body structure, and supports hot-swapping and interchangeability.
Key Features
- Electrical protection
