The HV SVC series products include TCR and MCR types. They adopt HV thyristor series technology and can be directly connected to 35kV, with a capacity of up to 180MVar. By real-time adjustment of the conduction angle of the thyristor valve, the purpose of rapid reactive power regulation can be achieved. In addition, the phase-by-phase compensation function of SVC can eliminate three-phase imbalance, and the filter device can eliminate harmful high-order harmonics and provide capacitive reactive power to the system to improve the power factor. SVC has unique advantages in the metallurgy, steel, mining industrial fields, especially in the treatment of large impact and unbalanced loads such as electric arc furnaces.
