Harmonic and Flickers Analysis Systems

Harmonic and Flickers Analysis Systems

The electric power makes different equipment can work through the power lines; but these same lines, whether electrical or data are likely to generate electromagnetic emissions radiated or driven.

That is why we must take into account that any non-sinusoidal periodic waveform can be represented as the sum of sine waves whose frequencies are multiple integers of the fundamental frequency, which we call harmonics. And these generate emissions that must be studied for the proper functioning of electrical equipment.

Harmonic emissions

  • Measurement of the levels of the harmonics generated by the equipment to the supply network (I £ 16 A / phase)
  • Frequency range: 0 to 2 kHz (harmonic 40)
  • Limits: Depends on the type of equipment.
  • They are a distortion in the waveform of the network signal produced by any type of active or electronic (non-resistive) load connected to said power network

  • The result is presented in graphs and tables with the measurement of the different harmonics.

Continuing with radiated or conducted electromagnetic emissions, other of the emissions to be taken into account is the “flicker”. This is produced in electrical networks by the action of disturbing charges, characterized by the consumption of rapidly fluctuating currents.

  • Measurement of the levels of voltage variations generated by the equipment to the supply network (I £ 16 A / phase)
  • Frequency range: 0 to 2 kHz (harmonic 40)
  • Limits: Depends on the type of equipment.
  • Voltage fluctuations are caused by loads connected to the power distribution system and produced by changes in the level of current and power of the same, for example electrical appliances, heating equipment, printers …
  • The result is presented in graphs and tables with the measurement of the different harmonics.
