Harmonic and flicker analyzer compliant with the latest versions of the IEC and JIS standards
The KHA series is a Harmonic/Flicker analyzer that complies to the standard of IEC/EN and JIS. The KHA1000 is dedicated for the single-phase equipment with two wires, and the KHA3000 applies to the test exceeding 16A of the single-phase and three-phase equipment (up to 40A per phase). Furthermore, the KHA series is compliant with both existing and the latest version of measurement technique standards, so you can simply select the measurements of the latest version of standard including the interharmonics, and for the conventional measurement that applies only the integral multiple harmonics without using any other device. In addition to the real-time display that can be used like an oscilloscope and FFT analyzer, the KHA series offers the real-time judgment of compliance with standards. Using the KHA series alone, you can judge test results and prepare result reports without using a PC. On top of that, you can easily configure the test system combined with the AC power supply (PCR-LE/LE2 Series) and the line impedance network (LIN Series) .

*1 The measuring window width is 0.2 second. In other words, it is 10 cycles at a fundamental frequency of 50 Hz and 12 cycles at a fundamental frequency of 60Hz. Interharmonic waves are measured at 5Hz intervals. Harmonic groups are measured out of harmonic waves and interharmonic waves. The values of harmonic groups are the results of measurement.
*2 The measurement window length is 16 cycles at the fundamental frequency. It is 0.32 second at a fundamental frequency of 50Hz and 0.266 second at a fundamental frequency of 60Hz. Interharmonic waves are not measured; only harmonic waves are measured. The values of harmonic waves are the results of measurement.
