Passive Harmonic Filters

For installations subject to a high level of harmonic pollution, the user may be faced with a dual requirement:

  To compensate for the reactive energy and protect the capacitors
  To reduce the harmonic distortion of the voltage to values that are acceptable and ompatible with correct operation of most sensitive receivers (PLCs, industrial computers, capacitors, etc.)
For this, WE can offer "passive" harmonic filters. A "passive" harmonic filter is a combination of a capacitor and an inductance in series, for which each tuning frequency corresponds to the frequency of an unwanted harmonic voltage to be eliminated.
