Ensuring the resistance of technical objects to the action of powerful electromagnetic fields of natural and artificial origin, caused by the use of military or terrorist means of electromagnetic impact, in emergency short-circuit modes, is an important technical problem, without the solution of which reliable and safe use of modern electrical, electronic and electrical equipment is impossible.
The purpose of the work is to create a set of measures aimed at ensuring the electromagnetic resistance of critical infrastructure facilities and defense facilities to the action of powerful electromagnetic influences according to EU and NATO standards.
A system of certification tests has been created in accordance with EU and NATO standards for electromagnetic resistance based on high-voltage stands created in Ukraine. For the first time, using mathematical and physical modeling of electrophysical processes, the formation of corona on grounded structures has been studied depending on the volume of zones in which the electric field strength exceeds the critical breakdown level. Mathematical models have been improved to determine the reliability of grounding and lightning protection systems under electromagnetic influence of artificial and natural origin on critical and military infrastructure objects, which differ from the known ones by taking into account an arbitrary number of underground and above-ground connections, and parameters of heterogeneous soil. An experimental high-voltage stand has been developed that implements tests on the influence of an electromagnetic pulse of a nuclear explosion on small-sized and component parts of military equipment objects. For the first time, statistical models have been developed to predict the total number of lightning strikes hitting critical infrastructure facilities, which, unlike existing models, take into account all possible locations of lightning leader channels, statistical distribution of potentials, average number of strikes, emergence of ascending leaders from structures, their dimensions and height, as well as the height and location of lightning rods relative to them.
The economic effect of implementing the results is based on reducing costs for eliminating failures in the operation of critical infrastructure (nuclear power plants, thermal power plants, oil and gas pumping stations, etc.) and ensuring the reliability of military equipment samples, which amounts to more than UAH 2.9 billion.
Number of publications: 10 monographs (textbooks, manuals), incl. 5 in foreign publications, 38 articles in journals included in category "A" (including 14 in foreign publications) and 26 articles in journals included in category "B".
