The 10kV Series Voltage Regulation Device (WVQC) is a new type of power electronic voltage regulator designed specifically to address issues such as large supply radius on 10kV lines resulting in low terminal voltage, large voltage fluctuation, voltage harmonic distortion, and three-phase imbalance. This device aims to eliminate electrical safety hazards for users.
