Summary: Beijing GERE active filter general performance is better than Europe brand. The items with red color is better performance.
Active harmonic filter other features
Have user-friendly operating software for easy operation.
Could withstand load short circuit shock, and restart after removal of short circuit.
Automatically eliminate resonance, not affected by electric network impedance and system impedance change.
Could simultaneously filter 2-50 harmonics in three-phase four -line distribution system, and is able to choose compensation or not for each harmonic from 2-50 harmonics .
The system has fast and complete fault self detection features, including undervoltage or overvoltage , overcurrent, fan failure , power devices over temperature , input fuse failure etc. fault self detection, all fault could be alarmed by APF and automatically taken corresponding actions.
APF’s high-frequency carrier itself can not be feedback to electric network.
Overcompensation must be avoided during filtering, i.e. APF could realize only filtering without generating reactive power to avoid over compensation completely, or by setting target power factor, the remaining energy after filtering is used for reactive power compensation.
Have soft start control loop to avoid too large inrush current while starting and to limit the current within rated range.
When the system is powered down, the filter could be automatically disconnected; After system recovery, the filter can be automatically restored.
