Induced disturbances by high voltage transmission lines on nearby stationary vehicles

This article discusses the safety issues related to electrostatic discharge phenomena caused by electric field induction from high voltage transmission lines. The main objective is to evaluate the inducing effects of an overhead line including towers and grounding networks on a nearby vehicle. Two different cases are considered. The first case studies the network under steady-state conditions while the second case treats a tower subjected to a single phase to ground fault. In both cases the induced current discharged from the vehicle to the ground is evaluated in order to define a severity index that is used to determine the location of the unsafe zones around the tower structure.
