Introducing Our New and Improved Active Harmonic Filters
Quality Energy • September 22, 2023
Quality Energy is proud to introduce our new range of Active Harmonic Filters. The new designs are proudly manufactured in our hub located in Moorabbin, Victoria, utilising premium modules from global manufacturers to create filters that exceed the highest Australian standards. The filters are built to last and equipped with various performance features. Read more to find out why Quality Energy's Active Harmonic Filters are the choice solution for harmonics mitigation.
What Are Active Harmonic Filters?
If you're experiencing power quality issues with your grid, such as harmonics, reactive power, and three-phase load imbalance, Active Harmonic Filters (AHF) can be a great solution. These filters are comprehensive and can effectively filter out harmonics in your power system.
How AHF Works?
Active Harmonic Filters clean out an electrical system's higher and lower-order harmonics. This process is also known as harmonic mitigation. The illustration below shows how AHF works to filter out harmonics in the network:
Quality Energy's Active Harmonic Filters
Quality Energy is proud to introduce our new range of Active Harmonic Filters. The filters have high input impedance and very low output impedance. Besides filtering out 2nd~51st harmonics, our AHF is available in 3-wire and 4-wire systems between phases and between phase and neutral. This helps to improve current and voltage imbalance on the steps and reduce the neutral current, which increases the safety of installation and allows sensitive loads to operate.
Other stand-out features of our Active Harmonic Filters include:
- wall-mounted and floor-standing options
- modular and compact design
- single cabinet design optimised for a single supply and reduced installation costs (hybrid solutions)
- easy installation and commissioning
- available in IP20 (wall-mount), IP30 and IP54 (free-standing) versions to suit a variety of applications
- 3-year warranty (conditions apply)
Australian Standards Compliance for Active Harmonic Filters
In Australia, the AS/NZS 61000.3.6 standard governs the acceptable level of harmonic voltage distortion and aligns with the IEEE 519 guidelines. If your power supplier or distributor is dissatisfied with the amount of voltage distortion at the point of common coupling (PCC), they may require harmonic filtering to comply with the Australian Standards. The 1992 edition of IEEE 519 specifies limits for both harmonic voltages on utility transmission and distribution systems and harmonic currents within industrial distribution systems. By managing the currents or impedances in the industrial facility, one can regulate harmonic voltages on the utility distribution since these voltages arise from the flow of currents through distribution system impedances.
Quality Energy's Active Harmonic Filters comply with Australian Standards, ISO 9001:2015 and ISO 14001:2015. We configure and build our Active Harmonic Filters in our manufacturing hub and factory at Moorabbin, Victoria and undergo rigorous factory testing (FAT).
Conclusion
Quality Energy's new and updated Active Harmonic Filters (AHFs) not only improve power quality from a technical standpoint but also reduce operational costs and boost overall profitability. Beyond the immediate financial gains, businesses embracing AHFs position themselves as sustainable businesses prioritising operational excellence.
