Power Quality Filters PQFI-PQFM-PQFK-PQFS

The ABB comprehensive solution for active harmonic filtering, load balancing and reactive power compensation.

The PQF active filter range offers ultimate filtering performance. It also excels through its stepless reactive power and load balancing features

  • Allows installations to run more efficiently
  • Filters up to 20 harmonics simultaneously (15 for PQFK and PQFS in 4-wire mode)
  • Filters up to the 50th harmonic
  • Filters zero phase sequence harmonics (3rd, 9th, ...) in the neutral (PQFK and PQFS)
  • Harmonic attenuation factor better than 97%
  • Fulfillment of international guidelines like G5/4, IEEE 519, etc
  • Operates with closed loop control for best accuracy
  • Has a programmable filtering strategy and free choice of harmonics selection
  • Auto-adaptation to network impedance changes
  • May filter without generation of reactive power/load balancing
  • May generate reactive power and control power factor
  • May balance the load current across the phases and between phases and neutral (PQFK and PQFS)
  • Has programmable task priorities
  • Two sets of compensation parameters for different load type compensation
  • Is not overloadable
  • Programmable stand-by and re-start functions
  • Fault and event logging with real time stamp
  • Direct connection up to 690V (CE-C-Tick) and 600V (cUL)
  • Top or bottom cable entry (bottom cable entry only for PQFS)
  • Easy commissioning - auto-detection of CT polarity and installed phase
  • Does not require detailed network analysis
  • Does not require special CTs
  • Is easy to extend on site
  • Comes factory tested
  • Optical fiber isolation between power and control stages
  • Advanced programmable digital I/O interface
  • Modbus RTU communication compatible
  • 3 phase 3-wire and 4- wire connectivity (PQFS)
  • Easy wall mounting design (PQFS)
  • Backlit user interface (PQF-Manager)

    A complete range covering all type of applications:
  • PQFM/PQFI for medium and large industrial loads
  • PQFK for commercial loads and industrial loads having substantial harmonics in the neutral
  • PQFS for commercial, residential and industrial loads
