Lightning accidents are frequent in Colombia. In the present investigation, a non-fatal accident is analyzed. For a better understanding of the accident, it was replicated in the laboratory a part of a reported case, in which a soldier, wearing a metallic identification pearl-like necklace, was struck by an indirect lightning current. Different 8/20 μs lightning impulse current amplitudes were applied to similar necklaces in order to determine its electrical parameters, such as dynamic resistance, the absorbed energy and the maximum withstand current. The preliminary experimental data obtained through the application of 8/20 lightning current impulses applied to necklaces is analyzed for a technical insight of the event.
