    System Components
     The Low Frequency measuring system is a compact solution to determine harmonic and flicker emissions generated by equipment connected to the public power main.
     HAR1000-1P is the single phase version and comprises a power amplifier, line impedance network, harmonics and flicker measurement, all in a single unit. HAR-EXT1000 added to HAR1000-1P provides full three phase capability.
     The hardware is controlled from a powerful user interface software (HARCS).


    Power Amplifier
     Using a novel technique to correct power main distortion reduces size, weight and cost compared to traditional systems. A small power amplifier is used to correct power main distortion and deliver a clean sine wave to an EUT. While the measurements are being made, the test voltage (U) at the terminals of the equipment under test, when operated according to the defined operating condition, shall meet the requirements laid down in the IEC standards.
     The power amplifier source impedance must be nearly 0ohm to prevent distortion of flicker results. The test voltage must be stable in amplitude and frequency to ensure correct results.

    Line Impedance Network
    Flicker measurements are small variations of RMS voltage caused by the EUT. In order to ensure that only effects from the EUT are measured, a conventional impedance of 0,4ohm + j 0,25ohm must be used. This is a real impedance included in the system.

    Harmonic Measurement System
    This can be configured to measure in accordance with the latest standard requirements (including amendment 14) and also the previous version. Providing an easy comparison of measurement results obtained from previous and new samples. Dual analysers simultaneously monitor the AC supply output and the distortion resulting from the EUT. Both voltage and current harmonics are measured and displayed for analysis purposes

    Flicker Measurement System
    The flicker analyser is a part of the system hardware and is compliant to the latest requirements of IEC61000-4-15. Specifically this means that dmax is the result of an average from 22 measurements taken from a total of 24. Verification of the flicker measurement system can be made using 33.3Hz modulation for 50Hz and also 40Hz modulation for 60Hz supplies. The inrush current capability enables measurement of dmax at 7%.

    HARCS software
    Provided as part of the system package, HARCS software is a powerful user friendly interface which allows the user to configure the system to perform measurements and displays the results in a convenient format. Unique features of HARCS software include:
    • Test Assistant
    • Harmonics inspector
    • Recorder function
    • ANASIM
    • Harmonic verification
    • Flicker verification
    Upgrading the HARCS to include the immunity package, provides a low cost means to perform additional testing for harmonic immunity, voltage fluctuations and ripple on DC supplies.

    Test Assistant

    Harmonics Inspector. Select individual harmonics to view additional information in real time.

    HARCS Recorder. Up to 8 different measurement parameters can be stored in the recorder. When a test is completed, data from the recorder can be “re-run” to assist in analysis of measurement results.

    HARCS ANASIM. Included in the HARCS package is the simulation program ANASIM.

    Verification. Perform a quick system verification for harmonics and flicker using internally generated signals.
