Profile:

Developed to meet stringent Chinese power grid requirements, the KDZD1256 system integrates high-voltage power sources, precision reference transformers, and intelligent control software. It enables full-system error calibration, communication verification, protection function testing, and automated report generation—delivering traceable, repeatable results aligned with JJG, GB/T, and State Grid technical specifications.

Features:

  • Full-system error calibration for integrated metering and protection devices
  • Support for electromagnetic, electronic, and multi-ratio current/voltage transformers
  • Comprehensive remote function testing: telemetry, telecontrol, and telesignaling (FTU/DTU)
  • Fault simulation: overcurrent, short-circuit, and single-phase grounding (metallic/low/high impedance)
  • Harmonic immunity and power quality impact assessment
  • Fully automatic or manual test modes via intuitive software interface
  • Automatic test report generation compliant with State Grid documentation standards
  • High-precision output with fine adjustment across voltage, current, phase, and frequency
