Method of lightning warning based on atmospheric electric field and lightning location data

In view of the shortcomings of traditional lightning protection measures in the initiative defense, it is necessary to research lightning warning technology, which can provide decision support for avoiding the lightning strike risks of infrastructures. This paper adopted atmospheric electric field and time-differencial calculation, combined with prediction of lightning moving trend based on Lightning Location System, achieved the technology of small-scale and short-time lightning warning for targeted areas. Finally, its effectiveness and practicality are verified by applying this method to transmission line in power grid.
