- Passive Filter
The harmonics mitigation by other techniques is very common but little bit expensive so we specially designed for the powenaac series an efficient Passive Filter for VFD’s., which can suit many such similar loads. Since all filter components are passive they are rugged, maintenance free, reliable and low cost. Moreover, the filter implementation procedure is relatively easy.
With simple structure, our Passive Filters have been extensively used for VFD harmonic mitigation. No involvement of electronic circuits, hardware and complicated control algorithms. Hence, our Passive Harmonic Filters are relatively inexpensive means for eliminating current harmonics distortion and improving the system power factor. Because of these two in one improvement our broad band filters usually have edge over the other effective filtering methods.
Benefits:
- Helps meet IEEE-519 requirements
- Gurantees THDi performance of 8% Max at 50% load, 5% Max at full load.
- Meets the voltage and current distortion limits of IEEE-519
- Saves energy by eliminating the wasted energy associated with harmonics, therefore reducing the true RMS KVA demanded from your power source.
- Suitable for speed controllers or inverters
- Reduces energy costs
- Increases equipment reliability by absorbing transients and voltage surges
- Increases equipments life by reducing heat associated with harmonic currents
- Improves power factor
- Reduces THD-V to meet power quality standards.
Filter Design Features:
- Uses fewer capacitors while maintaining 98% efficiency.
- More consistent power factor across the load range.
- Improves C/L ratio, which decreases potential resonance.
- Lowers capacitance resulting in less voltage rise at no load, at PCC (Point of Common Coupling) and on the DC Bus.
