The Pro Trend three-phase power quality analyzer is an advanced power monitoring instrument with an 8.4” color touch screen display. It helps to find, predict, and troubleshoot problem in three and single-phase power distribution systems.

Troubleshooting is faster with on-screen display of trends and captured events. A wide range of power monitoring data is collected, analyzed and tabulated to quickly identify areas of concern. Automated setups provide instant detection of circuits and configurations, guaranteeing that the instrument is ready to successfully collect data. The Pro Trend collects data at 256 samples per cycle per channel, meets IEEE 1159, IEC 61000-4-30 standards. The Pro Trend is perfectly suited for field use, having a weather-proof case weighing in at just 4½ kg.


  1. Real Time monitoring for simple troubleshooting
  2. Measure wide range of parameters, including true RMS and peak V and I; Frequency, Sag, Swells, Transients, Interruptions, Power and Power consumption, Demands, Harmonics up to 127th, Inter-harmonics, Flicker, Inrush and unbalance, Crest factor
  3. Records voltage, current, power, THD, Waveform snapshots and Flicker (IEC 868, IEC 61000-4-15 PST and PLT)
  4. Record Min, Max and AVG of several parameters on all 4 channels with resolution down to 1 seconds
  5. Easy to navigate, color graphic user interface
  6. Large color touch screen display – data can be viewed in real time using scope mode, meter mode, trend, harmonic spectrum or pharos diagram. Data can be viewed and zoomed for more details with the touch of a finger
  7. Generate PQ reports in few second
  8. Characterize and tabulate RMS events (IEEE & IEC)
