Main technical parameters

Typical applications

The YBYW-DJC-101 low-voltage integrated reading training device is designed as two independent platform areas, with each operating surface simulating a low-voltage platform area, namely platform area I and platform area II. The component configuration is consistent with the site. The device has the functions of fault setting, fault diagnosis and analysis, fault troubleshooting, and self recovery.

Including functions such as metering circuit faults, communication circuit faults, meter body faults, terminal body faults, household simulation, substation identification, cross substation simulation, load cutting, etc. for meters and collection terminals. The simulated energy meter and concentrator are developed based on real energy meters and concentrators, compatible with the specifications and communication protocols of State Grid (China Southern Power Grid), and support multiple communication methods. They also have fault simulation functions, which can simulate three common on-site faults: display, collection, and measurement. This ensures that the meter reading information of different students will not be the same, meeting the training needs.
