Abstract
The environment is filled with electrostatic fields of various origins. The negative influence of the electrostatic field requires the provision of electrostatic safety standards. So modeling of electrostatic fields is a topical research task. The electrization of objects is complex, depending on the many parameters process. The article considers the existing methods of studying electrostatic fields. The authors have justified the criterion for assessing the safety of an electrostatic field. The article proposes the developed advanced mathematical model describing the electrization of a complex, multi-layered object. Variable values in the proposed mathematical model are the main characteristics of the materials forming the layers of the modeled object, and the parameters of the condition of the environment. The constructed mathematical model of electrization of a complex object has undergone a successful experimental verification in field trials. Analysis of the experimental data confirmed the expected condition of the system, which is a complex object.
Highlights
The investigation of electrostatic fields surrounding human in everyday life and at work is a topical scientific task
Active use of the electric current energy leads to the formation of electrical charges on the external elements of household appliances and production structures. Another reason for static electricity charges on objects used by a person is the use of new materials
We estimated the magnitude of the electrostatic field strength modulus near the surface of the heat-shielding suit
Summary
The investigation of electrostatic fields surrounding human in everyday life and at work is a topical scientific task. Active use of the electric current energy leads to the formation of electrical charges on the external elements of household appliances and production structures. Spark gas discharge can cause primary injuries associated with the passage of electric current through the human body. They include: a burn with a spark of human skin, the ignition of hazardous substances in the environment. A huge temperature (up to 20000 K) is concentrated in the spark discharge channel This powerful heat flow causes the instantaneous ignition of the materials of the clothing package, severe burns and is the main damaging factor when exposed to an electric discharge directly on a person. The investigation of the conditions for the appearance and change of the characteristics of electrostatic fields is a topical scientific task
