[The world's first 500 kV economical high voltage AC current limiter] A few days ago, the world's first 500kV/90kA economical high-voltage AC current limiter developed by China Xidian Group successfully completed the manual short-circuit test and was successfully put into operation on the Shun-Guang-A line of the 500kV Guangnan Station. The successful operation of the project has filled the domestic economical AC ultra-large short-circuit current suppression technology gap, provided an economical and reliable solution for the suppression of high-voltage AC short-circuit current, and provided a strong guarantee for the reliable operation of the ultra-high-voltage large power grid.
