The principle of the SVG is very similar to that of Active Power Filter, as demonstrated in the picture below. When the load is generating inductive or capacitive current, it makes load current lagging or leading the voltage. SVG detects the phase angle difference and generates leading or lagging current into the grid, making the phase angle of current almost the same as that of voltage on the transformer side, which means fundamental power factor is unit. Delta’s PQC series SVG is also capable of correcting load imbalance.

  • Multifunctional: Reactive power and imbalance compensation
  • Excellent reactive compensation: High speed, Precise (-0.99≤Cosφ≤0.99), Step-less, Bi-directional (capacitive and inductance) compensation
  • Excellent imbalance correction: Both negative and zero sequence, mitigates neutral current
  • Wide input voltage & frequency range, adapts to tough electrical environment
  • Low thermal loss (≤3% of rated SVG capacity), efficiency ≥ 97%
  • High stability: Infinite impedance to grid, avoids harmonic resonance problem
  • Flexible application: Modular design, embedded in standard or customized cabinet
  • Easy installation and maintenance: Easy installation for APF module replacement and expansion
  • Wide capacity range: 50kvar~350kvar for a single cabinet, up to 10 cabinets in parallel
  • Environmental adaptability: -10~50°C temperature, compatible with diesel generators
  • Complete protection: Grid over/under voltage, SVG over current, over temperature, and others. All faults recorded inevent log, convenient for failure analysis
