Abstract: Calculation of vertical and horizontal electric field waveforms over perfectly conducting ground, associated with tilted lightning strokes, is performed by decomposing a lightning channel into numerous dipoles. It is pointed out that waveforms are greatly affected by three-dimensional inclination of the lightning channel.Lightning-induced voltages on an overhead wire over perfectly conducting ground, associated with tilted lightning strokes, are calculated based on the equivalent circuit incorporating the horizontal electric field. The accuracy is ensured by comparison with experimental results obtained by a scale model. It is clarified that the tilt of the lightning channel greatly affects the lightning-induced voltage on a distribution line.
