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.
