Abstract :
Secondary arc extinction characteristics on ultrahigh voltage (UHV) (1000 kV) transmission lines by high-speed grounding switches (HSGSs) were investigated using the high-power test facilities of the Central Research Institute of Electric Power Industry (CRIEPI). The extinction time of secondary arcs by HSGSs is compared with the auto-extinction time. The characteristics of arcs initiated in a large gap (6 m) are described.<>
