2.1 Three-Phase Synchronous High-Precision Sampling & Metering Unit
Equipped with industrial high-speed AD conversion chip, supporting 6-channel synchronous parallel sampling of three-phase voltage and current without timing deviation, eliminating power calculation errors caused by asynchronous sampling. Solidified high-precision metering algorithm achieves accurate parameter calculation under balanced and unbalanced three-phase conditions with 0.2-class industrial precision, meeting strict requirements for power station precision energy statistics, power assessment and load monitoring.
2.2 Full-Parameter Electrical Operation & Analysis Unit
All-dimensional electrical parameter calculation is completed locally without upper computer operation, including split-phase/total power, bidirectional electric energy, power factor, grid frequency, three-phase unbalance and harmonic distortion. The 10ms ultra-fast data refresh tracks real-time load fluctuations and captures dynamic electrical changes during equipment startup, load switching and grid disturbance, providing complete data support for system regulation and fault analysis.
2.3 Abnormal Data Locking & Fault Recording Unit
Built-in intelligent data identification algorithm automatically identifies voltage surge/sag, current overload, excessive three-phase unbalance and frequency deviation, locks and stores electrical data before and after faults. Integrated data filtering eliminates false data caused by instantaneous grid noise and electromagnetic interference, ensuring data authenticity and stability under harsh working conditions.
2.4 Industrial Bus Communication Transmission Unit
Built-in RS485 interface with native Modbus RTU protocol, directly connecting to PLC, DCS, energy management system and power monitoring SCADA. It supports remote data reading, parameter configuration, address and baud rate adjustment, featuring strong anti-interference and long-distance transmission capability for multi-module bus networking and centralized data upload.
