Abstract

Measurement of lightning surges caused by natural or rocket-triggered lightning strokes has been carried out on a 275 kV test transmission line since 1987. In November 1993, lightning currents at the tower top, the ground wires, the tower legs and the transmission line arresters, along with the voltages across the insulator strings were measured simultaneously four times. One of the four flashes was natural lightning, and its peak value was +132 kA. In this case, the arresters operated, and the insulator voltages where the arresters were equipped were controlled properly. The result of a multi-phase analysis by EMTP agreed well with the measured waveforms
