Sonel PQM-700

Portable power quality analyser prepared for measuring in all types of networks in any kind of environments including outdoors.

Product Description

Analyser measures and records according to the IEC 61000-4-30 CLASS S STANDARD.


  • Power to the analyser is supplied from tested mains (internal power supply) and is used in all types of networks from 64 V to 760 V, with particular emphasis on measurements at low voltage poles, due to the ease of connection,
  • Has an independent power supply socket, especially suited for voltage measurements for transformers and DC circuits,
  • Built-in real-time clock.

Possible measurements:

  • Measurements according to EN 50160,
  • Voltage L1, L2, L3,
    – average, minimum, maximum and instantaneous values, range to 760 V, ability to work with voltage transformers,
  • Current L1, L2, L3, N (four inputs),
    – average, minimum, maximum and instantaneous values, measurement current with range to 3 kA (depends on used clamp), ability to work with current transformers,
  • Crest factor for voltage and current,
  • Frequency from 40 Hz to 70 Hz ,
  • Active, reactive, distortion, apparent power, including the type of reactive power (capacitive, inductive),
  • Power recording:
    – Budeanu method,
    – IEEE 1459,
  • Active, reactive, apparent energy,
  • Power factor, cosφ, tgφ,
  • Up to 40th harmonics for voltage and current,
  • Total Harmonic Distortion (THD) for voltage and current,
  • Short-term (PST) and long-term (PLT) flicker,
  • Unbalance of voltage and current,
  • Current and voltage events registration including waveforms and RMS graphs half period.
