Research Abstract |
I evaluate the sparkover rate of a medium-voltage line associated with direct strokes to the line by using peak currents obtained at southern Kyushu by the JLDN (Japan Lightning Detection Network), one of the lightning detection network in Japan. In the evaluation, the correlation between the front duration and the peak currents is taken into account as well as the low-voltage line often installed below. In the estimation of the sparkover rate, the multiplicity of the strokes in a flash is assumed to be 2 based on the observed results by the high speed video camera. As the result, the estimated sparkover rate for a flash is in reasonable agreement with the reported rate.
