Harmonic filters

This system is a 20 kV 5th Harmonic Filter Bank, designed for industrial and utility power networks to mitigate harmonic distortion specifically the 5th harmonic, which is one of the most common and disruptive harmonic components generated by nonlinear loads such as variable-speed drives, rectifiers, and large power electronics.
The installation consists of multiple large filter reactors, capacitor bank units, and series resistors, all interconnected to create a tuned passive filter operating at 245 Hz (corresponding to the 5th harmonic on a 50 Hz system). The heavy-duty inductors and capacitors are arranged in segregated steel frames, with high-voltage bushings and robust busbar interconnections visible in the image. This configuration ensures precise tuning, stable operation, and reliable harmonic absorption under high-load conditions.
The nameplate provides detailed specifications:
  • Nominal Voltage: 20 kV
  • Nominal Reactive Power: 1.02 Mvar
  • Capacitor Bank Power: 2.386 Mvar at 31.21 kV
  • Filter Reactor: 54.2 mH inductance, 31/60 A rated current
  • Series Resistor: 4 Ohm with 18.20 kW thermal losses per phase
  • Protection Degree: IP00 (indoor installation)
  • Manufacturer: MR Reinhausen (2007)
Such harmonic filter banks improve power quality by reducing total harmonic distortion (THD), stabilizing voltage, protecting transformers and generators, and improving the efficiency of sensitive equipment. They are widely used in renewable energy plants, industrial facilities, substations, and heavy manufacturing environments.
