INPSVG LV Static Var Generator
The INPSVG is a dynamic reactive power compensation solution based on power electronics technology. It provides bidirectional and stepless reactive power regulation with fast response, maintaining stable power factor performance without over- or under-compensation.
Product Description
The INPSVG uses IGBT inverter technology and PWM control to generate compensation currents opposite to the load reactive current, enabling continuous capacitive and inductive reactive power regulation. In addition to reactive power compensation, it supports harmonic mitigation and three-phase unbalance correction through intelligent control and automatic capacity allocation. The system supports multiple compensation modes, parallel expansion, and wall-mounted or drawer-type configurations for flexible installation.
