summary
The loads of large welders, cranes, and adjustable speed motors cause a large fluctuation of reactive power,
triggering voltage drop and flicker of system and negatively influencing the electric equipment and control equipment of distribution system.
The intelligent reactive power compensator IVC compensates the reactive power of loads in real time with the uses of DSP and power electronic device. In this way, it can stabilize voltage, reduce flicker, lower a process defect rate through the improvement in welding quality, and increase an allowance rate of equipment through the rise in power factor.
