The Influence of Attachment Height on Lightning-Induced Voltages

The effect of the attachment height on the amplitude of lightning-induced voltages is evaluated by computational simulation. The reduction of voltage amplitude with increasing height is observed, and this effect is attributed to the electrostatic component of the induced voltages. Simulation of lightning strikes with typical parameters of first and subsequent negative strokes, including the height of attachment, indicated that induced voltages caused by first strokes have larger amplitude.
