Based on the atmospheric electric field monitoring data and lightning location data, the principle, method and process of lightning warning and forecasting is analyzed. The results show that lightning location and the distance between lightning location and atmospheric electric field instrument are major factors in warning and forecasting. It may be adjust the electric field threshold according to the specific terrain environment. The combination method of electric threshold warning and differential electric threshold warning is more effectively in lightning warning and forecasting, which minimize the loss to people's lives and socio-economic. © 2011 Springer-Verlag Berlin Heidelberg.

In order to analyze and improve the lightning shielding performance of transmission lines, working voltage is considered as an influence factor to the striking distance. The relationship between maximum striking distance and lightning polarity, or the size and polarity of working voltage is obtained. It is demonstrated with example that lightning shielding performance can be effectively improved through balancing the values of inclination angle θ, tower height h and shielding angle α. © 2011 Springer-Verlag Berlin Heidelberg.
