Nancal Electric NC SVG Series
Static Var Generator
NC SVG Series Static Var Generator (SVG) detects load current through an external current transducer (CT) simultaneously and analyzes the reactive component of load current by DSP controller, then generates PWM signal to IGBT inverter to generate reactive current and compensates load reactive current to meet the target of line power factor.
It can also compensate for harmonics and phase imbalance.
Compared with the traditional capacitor bank, SVG has the advantages of fast response and high compensation accuracy without under- or over-compensation problems.
