Electrical safety is important for all workers, but it should be a priority for electrical engineers. It's important that you are able to recognize electrical hazards and know how to protect yourself. Preventive maintenance is the best way to avoid electric shocks, electric arcs, and injuries caused by explosions. If you understand and respect electricity, always follow safety procedures, and use personal protective equipment, the risks to you and your coworkers will be minimized. This course explains the importance of electrical safety and the potential hazards associated with working around electricity. It contains five chapters:
· The first chapter is devoted to “Electrical Hazards”. It discusses the purpose of safety at work, the history of electrical hazards, standardization bodies, and statistics on electrical accidents.
· The second chapter focuses on presenting the “Nature of Electrical Accidents and the Dangers of Electric Current”. It covers the fundamentals of electric shock and electric current passing through the human body.
· Chapter 3 is devoted to “Protective Measures” and focuses on safety measures, protection of people and equipment, grounding diagrams (SLT), rules for the construction of electrical installations, namely work outside the power supply, work in the proximity of electrical installations, and finally work under power.
· Chapter 4 is devoted to “Safety measures against the indirect effects of electric current”. It deals with fires, harmful materials, explosions, noise, and vibrations.
· Chapter 5 is devoted to “Emergency measures and care”. It covers the correct response in the event of an electrical accident and first aid, such as assisted ventilation, cardiac massage, and care for burn victims.
Fundamental Electrotechnics is an important discipline that studies the production, transmission, conversion, and use of electrical energy. It forms the basis of industrial electrical engineering and combines the skills needed to understand the electrical and magnetic phenomena and their technical application in various electrical equipment and systems. In electrotechnics, the study of transformers (static machines) and rotating electrical machines (generators and motors) plays a central role, because these devices are the basis for the conversion and adaptation of electrical energy. For this reason, this course begins in the first part with a Review of Magnetostatics and Magnetic Circuits necessary for the study of single-phase and three-phase transformers in the second part, and Electric Machines in the third part. For each part, the main theoretical fundamentals and calculation tools are reviewed.
