Evaluation of lightning threat in distribution networks

The paper deals with the evaluation of lightning threat to distribution network feeders based on high-resolution flash density maps. High-resolution flash density maps with a resolution of 100 × 100 m are calculated from lightning information collected by a lightning location system. Lightning information used in a process of map calculation includes error ellipse, which is part of localization result, and is used for estimation of the location accuracy of a particular lightning event.
