HARMONIC FILTER RESISTORS

HARMONIC FILTER RESISTORS

Harmonic Filter Resistors
Filter Harmonics in Line
 The energy quality is very important for the devices used in the network. widely used power electronic equipments, arc furnaces, etc in the Line. It causes harmonic distortion in energy quality.

HARMONIC DISTORTION PROBLEMS
  • Overheating of the devices in the system
  • Overheating test results in insulation failures in devices
  • Failure to detect zero crossing in power electronic devices, wrong perception.
  • Noise and noise in the line.
  • Wrong Trip of relays.
  • It causes such problems.
APPLICATIONS

The Three-Phase Harmonic Filter is built of RLC elements. The resistance, inductance, and capacitance values are determined from the filter type and from the following parameters:

  • Reactive power at nominal voltage
  • Tuning frequencies
  • Quality factor.

 

The quality factor is a measure of the sharpness of the tuning frequency. It is determined by the resistance value.

Harmonic filter block models types:
