Electrical Safety, Health and Protection in Electrical System - Electrical Safety, Health and Protection in Electrical System
Description
Electrical shock happens when current passes through the body. Electricity travels through closed circuits, and people, sometimes tragically, can become part of the circuit. When a person receives a shock, electricity flows between parts of the body or through the body to a ground. This can happen if someone touches both wires of an energized circuit, touches one wire of the circuit while standing unprotected or touches a metal part that has become energized. An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the Earth's conductive surface, for safety and functional purposes.[1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation. Regulations for earthing systems vary considerably among countries, though most follow the recommendations of the International Electrotechnical Commission This course deals with the general rules of safety and electrical protection from currents and their danger to the human body with the design of the ground to protect against electrical hazards. Main topics: Introduction General rules for the safety of electrical and mechanical equipment. Electrical protection and identification and testing of procedures. Electrical protection from direct and indirect touch. Electrical danger to the human body. Grounding systems to protect against electric shock hazards. Design and implementation of earthing to protect against electrical hazards. The degree of protection according to international standards. Studying the conditions and locations of the installations for the means of operation according to the nature of the different systems. Occupational health and safety guidelines.
