Third Harmonic Filter HBF-T

Filters HBF-T are designed for the blockade of 3rd harmonic, reducing the currents of neutral in three-phase installation where there is installed connected between neutral phase. It is basically passive filters with a parallel combination of inductance and condenser, being his advantages of use the following ones:

  • Reduction of the third overtone until a 90%.
  • Significant Reduction of other overtones.
  • Reduction current of neutral absorbed.
  • Reduction of losses in the installation.
  • Reduction of the interferences.
  • Improvement of the power factor.
