The active harmonic filter (AHF) system is designed to eliminate harmonic oscillations and thereby reduce costs. It can be flexibly customized to achieve functions such as power factor improvement and load balancing, which can significantly improve power quality in power grids.
More Nengdu Active Harmonic Filters
Designed specifically for 400V low-voltage power grids, suitable for industrial & commercial buildings, and data centers. Effectively mitigates harmonics and improves power factor.
Suitable for 690V industrial power grids, matching high-power equipment and heavy-industry applications. Features stronger compensation capacity to meet high-voltage industrial power distribution requirements.
Used in low-voltage power distribution systems below 1kV, covering common specifications such as 400V and 690V. Widely applied in civil, commercial and general industrial fields with the broadest scope of application.
Applied in medium-voltage power grids of 1kV and above, allowing direct connection to busbars without step-down transformers. Mainly used in high-voltage scenarios such as substations, large industrial and mining enterprises, and new energy grid integration.
Advantages of Our Active Harmonic Filter
Capable of eliminating various harmonic disturbances with high precision to achieve comprehensive harmonic treatment.
Monitors load changes in real time, responds quickly and dynamically compensates for grid fluctuations.
Achieves comprehensive management of harmonics, reactive power and three-phase imbalance in one unit.
Operates in coordination with the power grid system without resonance risk, ensuring long-term stable performance.
Compact in size with small footprint, suitable for various space-constrained installation scenarios.
Automatically adjusts parameters under frequently changing load conditions to maintain stable operation.
Effectively reduces line losses and equipment heating, extending the service life of electrical equipment.
Supports modular parallel expansion for easy capacity upgrading without system reconstruction, delivering outstanding long-term scalability.
Modular Design of Active Harmonic Filter
The active harmonic filter adopts a professionally optimized modular design. The complete system consists of one or more standard APF filtering modules and an optional intelligent LCD touch screen. Each APF module is an independent and complete harmonic treatment unit, capable of stable standalone operation. Users can freely add or remove modules to flexibly adjust the system’s rated capacity according to on-site load requirements, without modifying the original system. It features the advantages of convenient installation, flexible configuration, and strong scalability.
Connected in parallel to the power grid for easy installation; multiple units can be connected in parallel for capacity expansion.
We are an industry and trade integrated new energy supplier, specializing in the R&D and production of NengDu Active Harmonic Filters.
