  • Abstract
    The Iranian isokeraunic map developed by the authors is presented. A statistical analysis of tower footing resistances of 400 kV lines in the Iranian national grid is also presented. An attempt has been made to evaluate lightning fifty-percent breakdown voltage (V50 ) across 400 kV insulators in Iran, according to obtained keraunic levels and probabilistic results of tower footing resistances. A comparison between calculated V50 and V50 of presently installed insulators of 400 kV lines in the Iranian transmission system is also presented
