    Product Information

I. Product introduction
RVT-D TFC dynamic reactive power compensation controller is designed for harmonic control of distribution network. It is designed according to ABB industrial standard, with the cutting-edge DSP anti-harmonic technology and anti-harmonic modular circuit, and can operate normally in harsh network environment. It is optimum for harmonic control, filtering and reactive compensation in low/high voltage networks.
