Physical Modeling of Electromagnetic Interferences in the Electronic Devices at Direct Impact of Lightning on Protection System of Building

The technique has been developed for analysis the noise immunity of electronic devices in the case of lightning strike impact on the lightning protection system on the basis of physical modeling. The mathematical models, the scheme of experimental stand and examples of parameters calculation for physical modeling of electromagnetic interference in communication line under the influence of magnetic fields of lightning discharge are offered. The example of physical modeling of electromagnetic interference in communication lines of electronic devices is presented.
