ABB Active Harmonic Filters
Reduce Harmonic Distortion and Improve Power Quality
ABB Active Harmonic Filters provide an effective solution for reducing harmonic distortion and improving the performance of modern electrical networks. Harmonics generated by variable speed drives, UPS systems and other non-linear loads can lead to overheating, nuisance tripping, reduced equipment life and increased operating costs. ABB’s proven PQF Active Harmonic Filter technology continuously monitors the electrical system and dynamically compensates for harmonic currents in real time.
Unlike traditional passive filter solutions, ABB PQF filters automatically adapt to changing load conditions, delivering harmonic mitigation, reactive power compensation and load balancing from a single platform. This helps improve system reliability, protect electrical infrastructure and support compliance with modern power quality requirements.
Suitable for industrial, commercial and infrastructure applications, ABB Active Harmonic Filters provide a flexible and scalable solution for improving power quality, reducing downtime and optimising electrical system performance. The addition of active harmonic filtering helps eliminate harmonics generated by AC Variable Speed Drives, inverters and other high-frequency switching loads, improving network reliability and protecting connected equipment.

PQF Features
The ABB range of PQF Active Harmonic Filters is available in ratings from 30Amps to 450Amps, and units can be arranged in multiples to obtain the required rating. The PQF Units can filter up to 20 harmonics simultaneously in 3 wire systems (15 harmonics in 4 wire systems), and up to the 50th harmonic.
PQF Manager
The PQF Manager provides a Graphical User Interface, which includes Measurement, Analysis, and Monitoring of all filter characteristics, as well as adjustment of certain settings. The PQF Manager is available with an optional Modbus communications link, and full setup and commissioning can be completed from a PC through the RS-232 serial port.
