Abstract
Based on the existing methodologies of evaluating the effect of powerful electromagnetic pulse on susceptible objects, the following methodology has been developed. The main goal is to evaluate the effectiveness of protection of radio electronic devices and electric circuit equipment. Usually these devices and equipment are part of an industrial facility. Thus, to evaluate the effectiveness of protection, an Electromagnetic Influence (EMI) safety factor was taken as a system elements stability indicator, where the sustainability of the system is characterized by a minimal number of its elements. Sustainability of the system is estimated in stages; the algorithm implementation methodology is introduced with mathematical and physical expressions. These expressions define the degree of EMI energy neutralization that penetrates through intakes in the screens.
Highlights
Finding solution to the problems related to the increasing firmness of Radio Electronic Facilities’ (RЕF) electric networks is becoming more and more important
There is an estimation methodology of electromagnetic impulse (EMP) effect on susceptible objects, but rarely there can be found any methodologies of protection efficiency estimation
These results of the research allow to conclude that the protection buffer is able to protect semiconductor devices from the Electromagnetic Influence (EMI) with certain parameters to provide them with conditions for reliable functioning
Summary
Finding solution to the problems related to the increasing firmness of Radio Electronic Facilities’ (RЕF) electric networks is becoming more and more important. This can be due to further growth of control system computerization, increasing usage of RЕF and electric equipment. It is based on screening, diverting destructive electromagnetic energy, its transformation into other types of energy and distribution by firmness of construction elements [4,5,6,7]. There is an estimation methodology of electromagnetic impulse (EMP) effect on susceptible objects, but rarely there can be found any methodologies of protection efficiency estimation (e.g. creation of protection based on transformation of EMP destructive energy, that penetrates through intakes in the screens of susceptible objects)
