Passive Harmonic Filter

Passive Harmonic filter is designed to provide an economical solution in Harmonic mitigation in Power Systems by maintaining THID 5% in compliance with current and voltage requirements of IEEE 519.They are used to suppress harmonic currents and decrease voltage distortion occurring in the sensitive parts of the Power system.

Passive Harmonic filters are an effective solution to filter harmonic currents produced by VFD and the source current THID to 5%.

Harmonic filter can provide solutions for below problems:

  • Nuisance tripping of circuit breakers.
  • Equipment malfunction.
  • Overheating of Components.
  • Increased installation and utility cost.


  • Motor Drives
  • Electronic Power Supplies and UPS
  • Power Grids
  • Variable Frequency Drives
  • Pump and Fan Applications.
  • Automation Equipment.
  • DC Chargers.
