Power quality analysis

We offer you power quality analysis service. With the advanced PQM-702 device and our knowledge and experience, we are able to measure, analyze and record 50/60 Hz power grids and power quality, in accordance with the European standard EN 50160 and the Regulation of the Minister of Economy of May 4, 2007 on detailed conditions for the operation of the power system.

The PQM-702 analyzer fully complies with the requirements of PN-EN 61000-4-30:2011 class A. It is equipped with 5 voltage measurement inputs, brought out by cables terminated with banana plugs: marked L1, L2, L3, N and PE.

The range of voltages measured by the 4 measurement channels, is a maximum of +/- 1500V.

Measured parameters

  • rms phase and phase-to-phase voltages, up to 760V (peak up to 1500V)
  • rms currents up to 3000A (peak up to 10 kVA) with flexible clamps (F-1, F-2, F-3); up to 1000A (peak up to 3600A) with C-4 or C-5 hard clamps; up to 10A (peak up to 36A) with C-6 clamps; or up to 100A (peak up to 360A) with C-7 clamps
  • Peak current and voltage coefficients
  • Network frequency in the range of 40...70 Hz
  • active, reactive, apparent powers and energies, distortion power
  • harmonic components of voltages and currents (up to 50th)
  • THDF and THDR harmonic distortion factor for current and voltage
  • loss factor K caused by higher harmonics (K-Factor)
  • active and reactive powers of harmonics
  • angles between voltage and current harmonics
  • power factor, cosφ, tgφ
  • asymmetry factor of three-phase networks and symmetrical components
  • flicker index Pst and PIt
  • interharmonic components of voltages and currents (up to 50th)
