The KHA3000 from Kikusui Electronics is a Harmonics and Flicker Analyzer that is designed for single and three-phase systems/equipment. It supports new and old harmonics/flicker standards of IEC/EN and JIS, such as IEC 61000-3-2 and IEC 61000-4-7, and is suitable for compliance testing. This analyzer is equipped with a function to measure the voltage, frequency, peak voltage and distortion rate of the AC power used for harmonic compliance testing to check whether or not the power supply is adequate for the intended test. It has a quality check function to measure current and voltage for adequate power requirements. The analyzer is suitable for tests exceeding 16 A of the single-phase and three-phase equipment (up to 40 A per phase). It can function as an oscilloscope and FFT analyzer, and provide real-time assessments for standards compliance.

The KHA3000 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. It can perform simultaneous measurements of the three-phase systems and displays real-time pass/fail results and spectrum data on the screen. It is available in an enclosure that measures 430 x 177 x 270 mm with GPIB, RS232C and USB communication interfaces. Its integration with the AC power supply (PCR-LE/LE2 Series) and the line impedance network (LIN Series) allows for convenient configuration of the test system.
