DESCRIPTION:Lightning can produce dangerous effects on power transmission l
 ines. Therefore\, reliable models to be inserted into power systems and ci
 rcuital simulators are of great importance when designing/assessing a tran
 smission or distribution network lightning protection system.\n\nThe lectu
 re starts with a brief description of the lightning phenomenon from a phys
 ical point of view. Then a detailed analysis of the models available in li
 terature to represent the lightning channel current and the resulting elec
 tromagnetic fields is presented. Particular attention is devoted to possib
 le strategies\, derived from the solution of inverse problems\, for the re
 construction of the lightning channel current starting from electromagneti
 c fields measurement. Finally\, the use of such current and field models a
 s inputs for power system overvoltage analysis is accounted.\n\nCo-sponsor
