[0002] Power engineering refers to engineering related to the production, transmission, and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. The grounding wire is a wire directly connected to the earth, which can also be called a safe return line. When in danger, it transfers high voltage directly to the earth. It is a lifeline that conducts unsafe charges or leakage currents generated by various reasons. In power engineering, the grounding wire is an important safety measure to ensure the safe operation of the power system and personal safety. The function of the grounding wire is to safely conduct the charges that may accumulate on electrical equipment to the earth, thereby preventing electric shock and reducing the risk of electrical fires. There are usually two types of grounding wires, directly connecting electrical equipment to the grounding body and indirectly connecting through one or more grounding buses. In power engineering, the installation and maintenance of grounding wires must strictly comply with relevant safety regulations and standards to ensure their effectiveness and reliability.
