Energoforma 3.3-12

Programmable three-phase source of current and voltage (phantom power)


The source was modernized to provide single / three-phase current and voltage test signals suitable for testing power quality according to IEC 61000-4-30 (including generation of harmonics up to 50th and interharmonics).


Energoforma 3.3 current and voltage (phantom power) source is designed to create a three-phase or single-phase system of currents and voltages, as specified by the programmable digital model of the signal.

Field of application

Calibration, accuracy tests and adjustment of:

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


  • Harmonic range from 0th to 50th
  • Library of standard waveforms (at least 200 profiles). It is maintained as a tool for imitation of typical AC distortions in electrical networks resulting from consumer loads of different types
