Characterization of lightning for applications in electric power systems

This document evolves as a continuation of a previous report (No. 94). Both documents are aimed at providing insight into lightning parameters for application in the electric power industry. It now discussed the role that different lightning parameters play in the creation of surge overvoltages that may produce line insulation flashover. The possibility to use lightning current estimates as the base predictor of other parameters is addressed both for negative and positive flashes. An overview of protection design is described.
