Voltage and Electrical Safety

Abstract

As is clear, the human body is mainly composed of water and electrolyte fluids. Accordingly, we can say that the human body generally acts as a conductor. The body also has resistance, due to which part of the electrical energy inside the body is converted into heat. The main factors affecting electric shock are voltage, current, resistance and other factors. Voltage, current and electrical safety are considered vital aspects in the design and operation of electrical systems. This article examines the effects of current-voltage and related matters on electrical safety and analyzes voltage drops and power fluctuations in cables and transmission lines, as well as the effects of different currents on the body. The main objective of this research is to evaluate the effects of high voltage and different currents on the health and safety of the body, maintain equipment and investigate methods for reducing voltage drops in electrical circuits. To achieve this goal, analytical and computational methods have been used to examine the effects of current and voltage drops and compare them with existing safety and security standards. The results of the study show that voltage drops in many of the systems studied are beyond the permissible limits of the standards, which can lead to reduced efficiency and increased electrical safety risks. Based on these findings, suggestions are made to improve the design and appropriate selection of cables and protective systems. This research can help improve the understanding and management of electrical safety and protection in various systems and help designers and engineers reduce risks and increase the efficiency of electrical systems.
