Remote Online Battery Capacity Verification Solution

New Products / New Technology

The remote online battery capacity‑verification solution addresses the centralized management and remote online capacity‑testing of batteries used in communication power supplies, operating power systems, UPS systems, and other applications at power plants, substations, converter stations, and similar facilities. It enables real-time acquisition of critical parameters such as battery voltage, current, internal resistance, and temperature, with data analysis and processing performed via a central capacity‑verification server. This facilitates remote online monitoring of battery banks, one‑click capacity‑verification discharging, segmented intelligent charging, smart operation and maintenance management, as well as equalization and activation functions. The system also offers features like capacity‑verification report generation, historical data retrieval, and real-time alarm notifications, ultimately achieving safe, efficient operations while reducing costs.

Residual Current Monitoring Device for AC Systems

New Products / New Technology

Dongfan Technology's independently developed AC system residual current monitoring device comprises a monitoring host, individual monitoring units, and a feeder‑trip module. Leveraging digital current synthesis technology and six measurement modes, it delivers high‑precision residual current monitoring at the microampere level, with power‑class EMC protection, and is fully domestically produced and under independent control. Primarily deployed in substation low‑voltage AC auxiliary systems, it addresses the longstanding challenge of delayed detection of insulation aging and leakage faults in conventional systems. Its distributed, quick‑install architecture and modular three‑tier design enable zero‑configuration commissioning, while supporting dual‑channel intelligent operation and maintenance—both local and remote—thereby effectively ensuring the safe and reliable operation of power systems.
