Protective-Coatings Providing Safety and Electromagnetic Durability of Electronics of the Smart Grids

Parameters of the protective coatings providing safety and electromagnetic durability of electronics of the smart grids from the electromagnetic disturbances of natural and artificial origin have been proposed. Considered protective coatings consist of magnetic and dielectric layers with losses. It permits to avoid reflections from the layers and to reduce levels of the electromagnetic field intensities of refracted waves due to their attenuation during propagation from layer to layer with increasing active losses. Parameters of such layers were determined with the help of the mathematical modeling of the electromagnetic processes. Made comparison with the analytical solutions of the results of numeric simulations proves their accuracy not exceeding 2 %. With the help of proposed coatings, refraction and reflection of the electromagnetic waves from conductive elements can be effectively reduced - by an order and more.
