Harmonic filters: anticipating network disturbances

Power plant

Electrical installations, for the use of industrial direct currents, of high power, often generate disturbances on the networks, which go as far as modifying the behavior of sensors and triggering the electrical safety devices.

METAL DEPLOYE RESISTOR offers a range of harmonic filters, as an anticipation solution to any technical distortion problems.

Filter, discharge & PIR resistors

Harmonic filters, mandatory for solving unexpected technical distortion problems

Current electrical equipment requires voltage stability and low harmonic distortions, as this can give rise to significant technical problems.

  • Increased heating,
  • Malfunction of control / remote management systems,
  • Strong current in the phases,
  • Resonance problems.

It is in a logic of anticipation and prevention of the risk of overheating of connections and premature wear of equipment, that harmonic filters are necessary.

They are basically made up of 3 elements:

  • capacitors,
  • inductors,
  • resistances.

These elements which will allow:

  • to adjust the filter more easily to its application,
  • to expand the bandwidth,
  • allow component fluctuations due to temperature.
