Active Harmonic Filter (AHF)
 

AHF is used for centralized harmonic suppression in a power system. AHF is an IGBT based power electronics device. It uses IGBT and inverter technology.
It actively eliminates 100% harmonic distortion and reacts instantly to varying loads. This is done by injecting additional currents as required in order to cancel the harmonic components of the non-linear loads.
 
Every consumer of Electricity Board at 415 V should possess, who experience harmonic related issues such as:
 
  • Overload
  • Malfunction in control circuitry
  • Heavy application of electronic drives
  • Nuisance Tripping & mis-coordination of relays
  • Over heating of system components
