Inhoud: The early-time responses of overhead lines to an exponentially decaying electromagnetic transient are considered. The early-time current, voltage, and radial electric field induced in a wire is investigated. A. transient electromagnetic plane wave produces the driving electromagnetic force for the wire. The wire is assumed to be infinitely long and perfectly conducting. The wire is situated above a finitely conducting plane earth. The plane wave is assumed to have its magnetic field perpendicular to the axis of the wire. The time history of the plane wave is described by a 5O kV/m decaying exponential pulse. It Is found that peak currents of over 5 kA and associated voltage crests of several megavolts occur for small incident wave angles. These values are comparable to small lightning strikes to power transmission line structures. The rates-of-rise of the induced currents are greater than 100 kA per microsecond which exceeds the maximum rate-of-rise of nearly all lightning negative first strokes.
