Abstract
Measurement of lightning surges caused by natural or rocket-triggered lightning strokes has been carried out on a 275kV test transmission li ne 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 sim ultaneously four times. One of the four flashes was natural lightning, and its peak value was +132kA. In this case, the arresters operated, and the insulator voltages where the arresters were equipped were cont rolled properly. The result of a multi-phase analysis by MTP agreed we ll with the measured waveforms.
