The basic introductory knowledge of electricians consists of both theoretical and practical parts, and here are some of the basics:
Fundamentals of Electricity: This is what you must understand, including the concepts of voltage, current, resistance, power, electrical energy, etc., as well as Ohm's law and basic circuit theorems.
Basic electrical technology: including the wiring of wires, the assembly of circuits, the replacement of fuses and other basic electrical technologies.
Safety knowledge: It is very important that electricians must strictly abide by safety regulations when operating, understand the hazards of electricity to the human body, use disconnecting switches, wear protective equipment, and so on.
The use of tools: such as how to use test tools such as ammeters, voltmeters, resistance meters, etc., as well as familiarity with commonly used electrical tools, such as pliers, screwdrivers, electric drills, etc.
Comprehension of circuit diagrams: In the work of an electrician, it is necessary to read and understand circuit diagrams. Therefore, it is necessary to be familiar with the symbols in the circuit diagram, understand their meaning, and be able to obtain the necessary information from the circuit diagram.
Basic electronic technology: understand the working principle and use of electronic components such as resistors, capacitors, inductors, diodes, transistors, etc.
Understanding Grid Systems: Understanding how grid systems work, such as transformers, power plants, circuit breakers, etc.
Familiar with relevant industry regulations and standards: including national and local power industry regulations, as well as relevant electrotechnical standards.
Mastering the above knowledge, combined with practice, can be used as an introductory foundation for electricians. However, electrician work is dangerous, so it is important to receive strict safety training and be guided by a professional before performing practical operations.
