ZDDQ-AHF Active Harmonic Filter

ZDDQ Active Harmonic Filter(AHF) is used to improve Power Quality through autonomous detection and dynamic filtering of harmonic currents present in power grid. ZDDQ Active Harmonics Filter is a perfect comprehensive solution to power quality problems with power grid such as harmonic wave, reactive power, and three-phase load unbalance. ZD AHF is connected in parallel in 380V~480V power grid, to detect the harmonic wave in power grid in real time, generate the reverse-phase compensation current through the converter, and dynamically filter the harmonic wave in power grid. The operation of AHF is unaffected by power grid structure and load type, and it will not produce harmonic oscillation with the system, thus perfectly realizing harmonic wave control of various loads. AHF can also realize dynamic reactive compensation, and control the capacitor switching, to improve the power factor of power grid. Meanwhile, AHF has the function of controlling the three-phase load current unbalance, thus comprehensively solving various power quality problems with power grid.

Two typical Advantages

-Adjustable and dynamic compensation

The type of pollution the filter set to focus on can be chosen by setting parameters correctly. ZDDQ Active Harmonic Filter is dynamic and continuously adjusts to changing circumstances. Parameters of the Active Harmonic Filter can also be adjusted at a later time. This makes the filter future-proof and effective throughout its lifetime.

-Fast response time

ZDDQ AHF have a very fast response time(No more than 5ms), so that harmonic pollution and malfunctions are almost immediately detected and eliminated before they cause any damage or problems.

Benefits of ZDDQ Active Harmonics Filters

Reduce Your Electrical Bill

With all those areas of energy reduction you will certainly see a reduction in your electrical bill. Businesses can expect up to a 25 percent savings on their electricity costs after installing a Harmonics Energy Filter. Those savings increase over time when you factor in the fewer glitches that force work stoppages as well as the reduced maintenance and increased longevity of your equipment.

Lower KWh Consumption

If you are trying to go green, or reduce your emissions even a little cutting the kWh your business is using is a great start. You will notice a drop in kWh right after installing a Harmonics Filter and further reductions over time.

More Efficient Energy Usage

The way Harmonics Energy Filters work is by cutting out the noise from the electrical current. If you look at a Waveform reading of your current electricity you will see that it has large peaks and dips but when you look after it has been filtered the wave is much tighter indicating a more efficient current. Think of it like taking a pixilated image and making it sharper and clearer.

• Prevention of breakdown and equipment failure
• Maximum utilization of installation capacity
• Improvement of energy efficiency
• Securement of reliability and continuity
• Reduction of service and maintenance costs
• Increased safety by reducing fire risk
