HARMONIC FILTER
Harmonic Filter
An active harmonic filter that detects and mitigates harmonics generated by nonlinear loads in real time, improving power quality, protecting equipment, and enhancing energy efficiency.
Features
Detects and mitigates harmonic currents generated by nonlinear loads in real time, helping prevent electrical accidents and improve energy efficiency through harmonic mitigation, unbalance compensation, and reactive power compensation.
-
Excellent Performance and Efficiency
- Reduces total harmonic distortion (THD) and compensates individual harmonics from the 2nd to 50th orders
- Improves power quality through displacement power factor (DPF) correction and power factor improvement
- Mitigates harmonic currents in real time using IGBT-based control technology
-
Enhanced Stability with Built-in Protection Circuits
- Built-in protection against short circuits, overvoltage, overcurrent, phase-sequence errors, and reverse current
- DC-link capacitor fault-diagnosis algorithm for preventive maintenance and service-life prediction
- Resonance-prevention design for stable operation
- Auto-recovery function and reset-button support for easier maintenance
-
Modular Design for Scalability
- Slim modular architecture improves system reliability and serviceability
- Freestanding and wall-mounted configurations maximize installation flexibility and space efficiency
