KHA3000
KHA1000◆ Supports new and old harmonics/flicker standards of IEC/EN and JIS.
◆ Using this device alone, measurement, analysis and report creation are possible.
◆ Basic measurements required at design and development sites are possible.
◆ Pass/fail judgment on limit value is possible.
◆ Real-time display of test status.
◆ Easy support with update kit when standards are updated.(for a fee)
The KHA series is a Harmonic/Flicker analyzer that complies to the standard of IEC/EN and JIS. The KHA1000 isdedicated for the single-phase equipment with two wires, and the KHA3000 applies to the test exceeding 16 A of thesingle-phase and three-phase equipment (up to 40 A 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.

Easy connection
The terminals for power input and load output are separated. This arrangement prevents
connection errors, thereby eliminating the risk of short-circuiting. Of course, voltage sensing
at the load is supported as well. KHA3000 offers both simplicity and expandability.

Features
Complied with the old and new versions of harmonicmeasuring instrument standards IEC61000-4-7
To select the standard, your desired combination can be arranged bychoosing from the limit value standarad and the testing measurement
standard. *It is only a combination made beforehand in KHA1000.

You can switch between
the old and new standards
to view the differences inreal time.

Conducting compliance testing without using a PC
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 ofa 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 canset up an easy-to-use test system whereby the operation panel of thisdevice can be used as the main console.

Supporting “repeatability” check

Equipped with a quality check function for thetesting power supply

Comparison can be made between the present measurement data andthe 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.

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 thepower supply is adequate for the intended test.

The IEC requirements

The measurement repeatability shall be within ±5% oflimit value.
IEC61000-3-12: The repeatability of the fundamental and 7th andlower harmonic orders shall be within ±5%.
The repeatability of the harmonics beyond the 7th harmonic ordershall be within ±10% or ±1% of the reference fundamental current,
whichever is larger.

4

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 to40th (0.3%)

S E R I E SCapable of simultaneous measurement of thethree-phases *Only Model KHA3000
The long-time flicker value in all segment time, “Plt” is specified to be 2
hours for the flicker monitoring period.
For three-phase equipment, measurement can be taken for eachphase, but that will take 2 hours x 3 = 6 hours.
Simultaneous measurement of three - phases c an shor ten themeasuring (testing) time to 2 hours.
◆ In order to fully cover the EUT input methods, you can set the wiring
method (single phase, single phase 3-wire, three-phase 3-wireand three-phase 4-wire). In addition, for the setting of L1, L2 andL3 (channels), you can select interlock or independent. This allows
appropriate measurement for equipment with largely different phasecurrents.
◆ In order to support measurement of each channel for 3 phases, thevoltage and current ranges were separated for each channel and
AUTO range was established for each. In addition, you can adjust
the DC offset for each range with a single touch.

Easy upgrade when standards are updated(supports the latest standards)
The unit can be easily upgraded from thefront panel using a CF card.*5*5: Users are requested to prepare CF cards.

Providing all major basic measurements
KHA Series are capable of measuring all major basic items including
voltage, current, power, power factor, apparent power, reactive power
and frequency.
It also provides other measurement functions such as waveform
monitoring and measurements of rush current and harmonic current in
low frequency zones.
These features make KHA Series a convenient routine work tool fordevelopment and design processes.

Rush current measurement
KHA Series observes the waveform of the rush current exceeding thetrigger level. It can also observe the voltage waveform. KHA3000 can
measure a rush current up to 160 Apeak, KHA1000 can measure arush current up to 80 Apeak.
The measuring range can be expanded to a high current by using an
optional external current sensor with updating the firmware.
A rush current can be measured while the EUT is connected. This saves you fromgoing through the trouble of preparing an oscilloscope and current probe. Set the
input phase angle of the AC power supply using the application software (SD006KHA, SD005-KHA), and turn on the unit. The rush current can be measured withgood reproducibility. The phase angle can be set in the unit of 1°.

Easy to build a harmonic test system without the use of a PC.

The OP02-KHAS(SPEC40425) is theresistive load device that confirms theoperation of the "harmonic current /flicker measurement system" performs
properly. The OP02-KHAS(SPEC40425)
is able to perform the daily check of theharmonic measurement standard "EN/
IEC61000-3-2", "EN/IEC61000-3-12",
and the flicker measurement standard"EN/IEC61000 -3 -3", "EN/IEC61000 3-11" for the "harmonic current/flicker
measurement system"◆ Calibration of ISO/IEC17025:
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 asachargeable option. (issued by the organizations shown in).

Calibration of KHA Series is carried out using the measuring instruments calibrated incompliance with ISO/IEC17025.
Calibration scope specified by ISO/IEC17025

Note that KIKUSUI cannot calibrate KHA1000/3000
in compliance with ISO/IEC17025.

National standards and international standards

Calibration laboratories accredited by JCSS/DANAK

AC shunt

Multi-meter

Thus, the calibration data for KHA Series that can be provided at the moment does notcontain 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.
