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

Main measurement functions are:

  • 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 and I, up to 50, optionally also power harmonics
  • Symmetrical components - three-phase system decomposition into a positive, negative, and zero component
  • All quantitates are calculated on 200 ms (10/12 period basis) according to IEC 61000-4-30
  • Voltage quality according to EN50160, IEC 61000-4-30 Class A (U, freq., THD U, flicker, unbalance, harmonics)
  • Voltage events according EN50160, IEC 61000-4-30 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) crosses specified limits
    • Waveform means raw voltage/current signal with sampling rate at 9600/19200/57600 per second, waveform length is up to 60 periods, with pre-trigger up to 1.2 second
  • Disturbances – in case of trigger, the device captures the half-period RMS quantities
    • Trigger can be activated by selected quantities (U, I, P, Q, S, freq., PF) crosses specified limits
    • Capture contains half-period quantities of voltage, current, frequency, power etc. (sampling rate is 100 samples per second), capture length is up to 10 minutes, with pre-trigger up to 30 seconds
  • Device is controlled by ENA-Touch application, data is viewed in ENA-Report
