relay tester kit


protection relay test equipment

All-in-One design, Integrated IEC61850 SV & GOOSE, 6I+7V analog channels output, Inbuilt GPS and IRIG-B, and other advance functions.

  •  With the function of test MU accuracy,time characteristcs,state mark,packet loss rate,harmonic analysis,signal analysis, voltage and current phase detection, transient characteristic verification. Can test all aspects of MU functions and performance.
  •  Except MU test and traditional protection relay by analog input, KF920 also can test IED in intelligent substation which comply with IEC61850 standard.
  • 7 phase voltage and 6 phase current output, Maximum voltage is 310V/phase. Maximum current is 32A/phase(Max 192A in parallel six phase), 13 channel low-level signal output.
  •  Analog signal sampling use industrial-grade high-precision ADC, output accuracy can reach 0.05%. Absolute delay, time jitter test accuracy is better than 1μS.
  •  Perfect self-test and prompt. The system is stable ,device performance will not be changed by long time running; The system can detect abnormal situation and give warning.
  • 12.1 inch touch sreeen, Built-in windows operating system. Compact structure, safe and easy to portable
  •  Can be used as a record and waveform analyzer.
  • Built-in high-precision analog amplifier, Which can provide 6 × 32A AC current source and 7 × 310V AC voltage source.
  • Built-in 100M fiber Ethernet port(2 Pairs,LC Type) and IRIG-B Port(In/Out).
  • Provide merger unit accuracy test function (Amplitude error, Phase error, etc.).
  • Simulate Binary I/O signal (Hard contact or GOOSE), Which comply with merger unit voltage switching,voltage parallel logic function test.
  • Can test Merger Unit time characteristcs ,such as time sending accuracy,time receiving accuracy.
  • Have Message analysis and statistics function which can real-time analyze merger unit output SMV, GOOSE message. Have Protocol consistence test and abnormal message check and statistics function.
  • Can test Merger Unit self-check and error handling mechanism through sampling quality,signal mark in GOOSE , warning information define in Goose signal.
  • Real-time display waveform,binary state and previous switch trip time in message electrical parameter. Mark time scale in SV message through hardware to count and evaluate time dispersion of merger unit SV message.
  • Record message data in 1 minute, analyze/compare time scale and amplitude data of each sampling point, display amplitude and time scale statistical results of error distribution curve and Max error.
