The Frequency Distribution of Current Magnitudes of Lightning Strokes to Tall Structures

The frequency distribution of stroke current magnitudes proposed in the literature are examined to evaluate the influences nces that the height and type of structure have on the distribution of current magnitudes observed in the structures. These analyses have been performed using a three-dimensional electro-geometric model1. Results indicate that both the height and the type of the structure on which current measurements are made significantly influence the observed frequency distribution. It is suggested that these effects contribute to the differences existing between alternative distributions found in the literature.
