For the protective grounding of electrical equipment, what type of grounding electrode should be chosen? How deep should the grounding electrode be inserted into the ground?
Based on the requirements for ground resistance, select and calculate the type of grounding electrode, the number of grounding electrodes, and their distribution pattern.
The \"Manual for Industrial and Civil Power Distribution Design\", the \"Manual for Power System Design\", as well as standard textbooks on \"Factory Power Supply\" all contain detailed descriptions; it is recommended that you find a relevant standard or a book intended for college and vocational school students to consult.
