HARMONIC FILTER
Harmonic Filter
An active harmonic filter that analyzes and controls harmonics generated by nonlinear loads in real time, stabilizing power quality while helping protect equipment and improve energy efficiency.
Features
A device that detects and cancels harmonic currents generated by nonlinear loads in real time,
helping prevent electrical accidents and save energy through harmonic mitigation, unbalance improvement, and reactive power reduction.
-
Excellent Performance and Efficiency
- Supports total harmonic distortion (THD) reduction and compensation by individual order (2nd to 50th selectable)
- Improves power quality through displacement factor (DFT) correction and power factor improvement
- Real-time harmonic current cancellation using IGBT-based control technology
-
Enhanced Stability with Built-in Protection Circuits
- Multiple protection functions: short circuit, overvoltage, overcurrent, phase-sequence error, and reverse-current sequence protection
- Preventive maintenance and life prediction enabled by DC-link capacitor fault diagnosis algorithm
- Resonance-prevention design for stable operation
- Auto-recovery and reset-button support for easier maintenance
-
Modular Design for Scalability
- Slim-module structure improves system reliability and serviceability
- Freestanding and wall-mounted configurations maximize space efficiency
- Optimized for three-phase power systems to maintain stable power quality
-
Stronger Robustness with Intelligent Algorithms
- Proprietary intelligent FFT algorithm maximizes harmonic detection and compensation performance
- Automatic system impedance calculation helps prevent resonance in advance
- High system reliability for stable long-term operation
-
Graphical User Interface (GUI)
- 7-inch central HMI for an intuitive user experience
- Real-time display of voltage, current, frequency, THDi (before/after compensation), active/reactive/apparent power, and other key data
- User-oriented interface for efficient monitoring and control
