Energotester PQP-A

Three-phase Power Quality and Energy Analyzer

ACCURACY CLASSES: 0.1, 0.2, 0.5



  • Designed to measure and log electrical signals and power quality parameters as defined by IEC 61000-4-30 (class A)
  • Measurement and logging of basic electrical energy values in single- and three-phase networks including RMS of currents and voltages (no matter what their waveforms may be - sinusoidal or not), active, reactive and apparent power and energy
  • On-site connectivity and performance check of active/reactive power and energy meters and instrument converters of current, voltage, active and reactive power
  • On-site connectivity and performance check of single and three-phase electric energy meters without breaking into current circuits
  • Measurement of secondary circuit parameters (load power in secondary circuits of instrument transformers and voltage drops) as applied to Automatic Meter Reading and Billing systems
  • Measurement of losses in power transmission lines

Statistic power quality data are logged and transferred to a PC including:

  • Power quality values (as defined in IEC 61000-4-30 and IEC 61000-4-7), with logging capacity of 512 days
  • Magnitude and duration of voltage dips and swells
  • Flicker short-term severity values
  • Electrical network parameters with logging capacity of:

- 24 hours at 3 sec averaging time
- 200 days at 10 min averaging time

Test reports are generated in EmWorkNet program.

Note! We offer various training programmes for users of Mars-Energo instruments and software.
