2. The grounding of the power supply system is divided into protective grounding and working point grounding. Protective grounding is the grounding of the shell of live equipment. The working point grounding refers to the neutral line grounding. The grounding grid method is the same as the lightning protection grounding method, and the grounding resistance is less than ohm. If the requirements are not met, a grounding electrode should be added. If the conditions are not good, electrolyte should be added and/or the soil should be replaced. The working ground and protective ground are drawn out independently in the power distribution room, and the system can be combined into one. Working mode, such as the ground wire and neutral wire are separated, or they can be combined into one and lead to the electrical system (or equipment). The grounding system must be grounded repeatedly. There are also independent ways and systems. Ground Zero can no longer become one. 3. Instrument grounding system. The ground resistance of this system is less than ohms and cannot be connected to the lightning protection ground.
4. Anti-static grounding, such as oil pipes, etc., must be reliably grounded every 3 meters (elbow) (can be system or independent), with resistance less than 3 ohms
