Overview APF /SVG module + HYBAGK anti-harmonic capacitor (combined set). The APF or SVG module is installed in the cabinet and equipped with incoming circuit breakers and quick-fuse The capacity of HYBAGK capacitor module is any combination of 5kvar ~ 60kvar; the capacity of APF or SVG module is 50A (35kvar), 100A (70kvar), 100kvar optional. Ventilation design on the back, with ventilation filter holes. Capacitor switching is controlled by APF / SVG, which is more intelligent. The advantages...

HYAPF active power fil...
Overview HYAPF / HYSVG detects the load current in realtime through the external current transformer (CT), calculates the harmonic/reactive component of the load current through the internal DSP, and sends it to the internal IGBT through the PWM signal, then generate a compensating current with the same amplitude but opposite phase angles to the detected harmonics / reactive power to achieve the filtering/compensation function. ● Harmonic compensation: APF can filter 2 ~ 50 times random harmo...

Overview Three-phase imbalances are common in low voltage distribution networks. Due to the existence of a large number of singlephase loads in urban and rural networks, the current imbalance between the three phases is particularly serious. The current imbalance in the power grid will increase the loss of the line and transformer, reduce the output of the transformer, affect the operation safety of the transformer, and cause zero drift, resulting in three-phase voltage imbalance, and reduce ...

Intelligent Power Capacitor: Smarter Reactive Power Compensation
An intelligent power capacitor takes the familiar idea of power factor correction and makes it self-aware. Instead of a fixed capacitor bank that sits there waiting for an external controller to tell it what to do, this device monitors voltage, current, and reactive power on its own and decides w...

What Power Quality Actually Means for Your Facility
Power quality refers to the stability and cleanliness of the electrical supply feeding your equipment steady voltage, smooth waveform, and minimal noise or distortion. When power quality degrades, the symptoms are familiar: lights flicker for no obvious reason, variable-speed drives trip offline,...
