Static VAR Compensator (SVC)

A weak power grid usually suffers from the voltage drop due to heavy loads. Many industry loads, like mining machine and electric furnace, always generate large amount of harmonic currents, heavy voltage flickers and drops. These problems can easily interrupt power supplies, lower product quality and even reduce productivity.

To help utility and industry customers improve power quality, NR offers SVC solution to regulate reactive power and voltage so as to improve power quality in a very short period. The SVC system employs innovative valve technology and reliable thyristor triggering method, comprising compact valve banks, efficient cooling system and advanced protection and control system. It has gained extensive market value for its fast response time and low-cost maintenance schemes. NR’s
