      PQA-Portable Power Quality Analyzer

      • HIGHLIGHTS

      This unique and portable power quality analyzer uses modern control features with optional touchscreen to accommodate all requirements. 

      With a large storage capacity it includes the following features: GPS, harmonic analysis up to 9 kHz, power and energy analysis, disturbances, waveform capture and symmetrical components.

      The firmware calculates power quality parameters according to EN50160. It fully follows requirements as described in IEC 61000-4-30, Ed. 3 Class A and others (61000-4-7, 61000-4-15).

      Power Grid Monitoring Success

      With over 25 years of grid power quality experience, we provide state-of-the-art analyzers and monitors for every scenario. Our portfolio of products and know-how ranges from global phasor monitoring systems (WAMS) through metering and comprehensive evaluation of the quality of supplied electricity across the country. This includes the detailed energy monitoring of industrial plants down to individual machine consumption. These instruments are used worldwide across almost all continents.

      Measurement Features

      • U, I, P, Q, S, frequency, THD U, THD I, power factor, energies – AP, AQ, AS, APin, APout, all quantities are per phase and total.

      • Harmonics – U, I, P, Q up to 50th harmonic, U and I also as 200Hz spectra (0-9 kHz).

      • Symmetrical components – three-phase system decomposition into a positive, negative, and zero components.

      • All quantities are calculated at 200 ms (10/12 period basis) according to IEC 61000-4-30, Ed. 3.

      • Voltage quality according to EN50160, IEC 61000-4-30, Ed. 3 Class A (U, freq., THD U, flicker, unbalance, harmonics).

      • Voltage events according EN50160, IEC 61000-4-30, Ed. 3 Class A (dip, swell, interruption – time, extrema, length)

      • Waveform capture (transients) – in case of trigger, the device captures the waveform.
        • Trigger can be activated by selected quantities (U, I, P, Q, S, freq., PF) crossing specified limits.
        • Waveform means raw voltage/current signal with sampling rate at 9,6 k/19,2 k per second, waveform length is up to 60 periods, with pre-trigger up to 1.2 second.
        • Transient sampling rate of 24kSa/s.
      • Disturbances – in case of trigger, the device captures the half-period RMS quantities.
        • Trigger is activated by selected quantities (U, I, P, Q, S, freq., PF) crossing specified limits.
        • Capture contains half-period quantities of voltage, current, frequency, power etc. (sampling rate is 100/120 samples per second), capture length is up to 15 minutes, with pre-trigger up to 30 seconds.
