EMC aspects in a steel structure struck by lightning

The EMC analysis of a complex steel structure struck by a direct lightning, based on a simulation model developed by the authors, is here presented. For this proposal, simulations of the resulted magnetic field, as a function of the time, in the places where the higher susceptibility equipment will be installed, considering different lightning struck points, are carried out and these results are compared with some established limits. Some conclusions are presented, pointing out the advantages of the considered EMI prediction model during the design of the electrical and electronic installations, when lightning effects should be considered
