Energoforma 3.3-12M

Energoforma 3.3-12M

This source of AC current and voltage (phantom power) generates a single- or three-phase system of currents and voltages according to a user-specified model.


Accuracy tests, calibration and verification of:

  • Instruments for active, reactive, and apparent power / energy measurements (including energy meters)
  • Instruments for power quality measurements (IEC 61000-4-30 and IEC61000-4-7)
  • Instruments measuring RMS values of voltage and current within commercial frequency range.


  • Harmonic composition: harmonics up to 50th and interharmonics up to 50.5th
  • Memory capacity assigned to the library of signals imitating distortions in electrical networks typical for different groups of consumers: 200 waveforms as a minimum.
