Harmonic / Flicker Analyzer Harmonic/Flicker Analyzer Supports harmonic and flicker compliance testing of single-phase and three-phase equipment IEC61000-3-2 Ed3.0/A2 (Harmonics for 16A or less) IEC61000-3-3 Ed2.0, Ed1.2 (Flicker for 16A or less) IEC61000-3-11 (Flicker for over 16A)* IEC61000-3-12 (Harmonics for 75A or less)* IEC61000-4-7 Ed2.0/A1, Ed2.0, Ed1.0 (Interharmonics ON/OFF) *Only Model KHA3000

Harmonic /Flicker Analyzer 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...

◆Allows changes in the test conditions while monitoring VIEW key You can change the test conditions with the monitor screen unchanged. ◆Capable of simultaneous measurement of the three-phases 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 each phase, but that will take 2 hours x 3 = 6 hours. Simultaneous measurement of three-phases can shorten the measuring (testing) time to 2 hours. Impedance network Equipment under test (EUT) U ◆ In order to fully cover the EUT...
