The characteristics of the residual voltage of a surge protective device (SPD) connected to an overhead distribution line due to nearby natural cloud-to-ground lightning and to rocket-triggered lightning are analyzed in this paper. The residual voltage of the SPD is found to be closely related to the ground potential rise at the grounding terminal of the SPD. For natural lightning occurring 1.8 km...
Residual voltage of SPD connecting to overhead line is closely related to earth potential rise at the grounding terminal of SPD. Characteristics of the SPD residual voltage caused by natural lightning and artificially triggered lightning were analyzed in this paper, and the results show that: 1) In case of the natural lightning, the earth potential can be regard as zero, and the voltage difference...
