Experimental study of transients and electrical fields caused by lightning flashover in the uhvdc converter station

When lightning strikes the DC transmission line and causes flashover, the transients propagating in the primary circuit and impulse electromagnetic field generated in the station might cause interference or even block fault of the UHVDC system. In this paper, artificial short-circuit (DC line to ground) experiments are conducted out on an operating ± 800 kV… CONTINUE READING
