Our Activephase series is an advanced modular Active Harmonic Filter (AHF) system. The AHF system is constructed of one or several filter modules with the system controller.

Filter modules and controller, both are embedded in our stardard cabinets. CT terminations are fixed in a standard cabinet, and the AHF capacity can be configured ac cordingly to user requirement.

The filter capacity can be easily expanded at the user's site by adding extra filter modules as per site  requirement

  • Supports flexible configuration and capability to expand vertically as well as horizontally
  • Compatible with diesel generators & harsh ambient (Temp up to 50C)
  • Eliminates Harmonics, avoiding risk of resonance
  • Highly flexible and scalable solution
  • Lower Current could reduce thermal loss in power cables & transformer
  • Reduce Voltage Distortion and Fluctuation to extend
  • Service time of electric devices
  • Suppressing harmonics & reactive power reduces the Total current, so more loads can be driven by the same transformer
  • Increase power factor, avoid reactive power penalty Can compensate from 2nd to 51st order harmonics  Adaptability
