KF920 Earth impedance test device / relay / automatic / primary injection

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.
