According to the comparability of lightning discharge and rod-plane gap discharge
a simulated experiment was carried out to determine the relation between striking distance factor and other parameter.Experimental result indicates that striking distance factor K decreases with the increase of line height h.The relation between K and h achieved from experimental data is: K=1.032 3-0.004 1×h.Based on the electromagnetic theory
some accidents on real transmission lines are explained satisfactorily with this expression.Therefore
the expression can be used in lightning protection calculation of UHV transmission lines.
