This paper presents the horizontal electric fields computed at the ground surface and at different depths below the ground surface due to a nearby lightning stroke. Using the horizontal field thus calculated at various points, the induced voltage on a buried cable has been computed using a coupling equation, which incorporates the transfer impedance of the cable. The influence of ground parameters like conductivity and relative permittivity have been considered in the calculation of electric field and hence the induced voltages.
