Abstract
This paper attempts to investigate the horizontal conductor lightning striking distance estimation.
An electromagnetic model was proposed to model a vertical downward lightning leader and an
infinite grounded horizontal conductor by using the charge simulation method (CSM) to calculate
the lateral striking distance. A formula between the lateral striking distance, the lightning current,
and the horizontal conductor height was estimated. The proposed formula was compared with
electromagnetic model and previous formulas. By the use of a similar methodology, a horizontal
conductor voltage coefficient had been proposed and estimated. The proposed voltage coefficient
was used to modify the electrogeometric model in order to study lightning striking rates of an
unshielded horizontal conductor for different heights at either AC or DC voltages.
