Research of some problems of electrical safety

The article describes in detail the causes of electric danger, the types of its effects on the human body, and ways to protect against the danger. Schemes of connecting people to single-phase and two-phase current circuits and their possible consequences are investigated. The possible consequences of residual charge, induction charge, static electric charge in the circuit and their influence are reflected in the article. It is shown on what factors step tension depends on, how this tension affects people. The formation of the potential difference in the air gap, the piercing due to the decrease in the electric strength of the air, the effect of the thermal damage of the arc discharge on the body were analyzed.
