Overview
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) .
*Measurement beyond 40 A/phase can be supported by firmware ver.2.00 or later of KHA3000, and clamp-on probe on shelves.
Complied standards
Compliance with the following standards can be tested.
User-friendly terminals and interfaces
Features
Complied with the old and new versions of harmonic measuring instrument standards IEC61000-4-7
The choice of standards is divided into limit value standards and measuring instrument technical requirements standards, which can be freely recombined (only pre-made combinations are available for KHA1000).
No need for a PC for compliance testing
Using this device alone, you can perform a series of test processes – from setting test conditions and running the test to judging test results against limit values and outputting result reports – without the use of a PC. The device displays pass/fail results and spectrum data on the screen in real time. What’s more, since KIKUSUI’s PCR-LE/LE2 Series AC power supply can be controlled from KHA Series, you can set up an easy-to-use test system whereby the operation panel of this device can be used as the main console.

Supporting “repeatability” check
Comparison can be made between the present measurement data and the past measurement data to check whether or not the error is within the specified allowable range. This feature is helpful in evaluating the “repeatability” that is required in harmonic compliance testing.
The IEC requirements The measurement repeatability shall be within ±5% of limit value. IEC61000-3-12:The repeatability of the fundamental and 7th and lower harmonic orders shall be within ±5%. The repeatability of the harmonics beyond the 7th harmonic order shall be within ±10% or ±1% of the reference fundamental current, whichever is larger.
Equipped with a quality check function for the testing power supply
KHA Series are equipped with a function to measure the voltage, frequency, peak voltage and distortion rate of the AC power used for harmonic compliance testing in order to check whether or not the power supply is adequate for the intended test.
The IEC requirements IEC61000-3-2:The voltage harmonics must be the following values or less. 3rd (0.9%), 5th (0.4%), 7th (0.3%), 9th (0.2%), even harmonic order between 2nd and 10th (0.2%), 11th to 40th (0.1%)
IEC61000-3-12: Output voltage and harmonic inclusion rate under no load 5th (1.5%), 3rd and 7th (1.25%), 11th (0.7%), 9th and 13th (0.6%), even harmonic orders between 2nd and 10th (0.4%), 12th and 14th to 40th (0.3%)
Easy to upgrade when standards are revised (to comply with the latest standards).
The unit can be easily upgraded from the front panel using a CF card.*Users are requested to prepare CF cards.
Basic measurements are also taken care of.
Voltage/current/power/power factor/apparent power/reactive power/frequency can also be measured. Waveform monitoring, inrush current measurement and harmonic current measurement in the low-frequency band are also possible, making it a convenient tool for daily work at development and design sites.
Inrush current measurement
The inrush current waveform above the trigger level is observed. Voltage waveforms can also be observed: the KHA3000 can measure inrush currents up to 160 Apeak and the KHA1000 up to 80 Apeak. With a commercially available clamp-on probe (voltage output type) and firmware updates, even higher currents can be measured.
The inrush current can be measured while the EUT is connected. This eliminates the need for a separate oscilloscope or current probe. Inrush current measurements with good reproducibility can be made by setting the AC power input phase angle using the application software (SD006-KHA, SD005-KHA) and turning it ON. The phase angle can be set in 1° increments.
About ISO/IEC 17025 calibration
Provided with calibration/data (measuring equipment in use)
In order to meet the customers’ request for traceabity of the calibration of KHA Series for ISO/IEC17025, we have established the “traceability system” as shown in the figure below. (It is used for the production and inspection of KHA1000/3000.) When the “Certificate of traceability with Calibrator Data” is requested, a copy of the “Calibration Certificate” can be also attached as achargeable option. (issued by the organizations shown in yellow in the figure).
-
That KIKUSUI cannot calibrate KHA1000/3000 in compliance with ISO/IEC17025. Thus, the calibration data for KHA Series that can be provided at the moment does not contain of “the Expression of Uncertainty”. A copy of the data that contains of “the Expression of Uncertainty” for the measuring instruments used for calibration can be attached as a chargeable option.
If you need data issued by accredited calibration laboratories (with the logos), please contact our sales representatives. - If you require data issued by an accredited calibration institute (with logo/mark), please contact our sales representative.

Use the terminal “I Monitor” and “V Monitor” on the back of RIN.*In order to satisfy the voltage drop of 0.5Vrms in the measurement specified in the IEC61000-4-7 Ed2 , it is recommended that the wiring between the OUTPUT and the SOURCE terminal of the KHA series must be connected short and use the thick cable as possible. (at least thicker than 8mm2, 16mm2 to 22mm2 for measuring more than 16A).
