Should the user hang the grounding wire or the power supply bureau hang the grounding wire for the maintenance of the high-voltage incoming cabinet in the user substation?

When the high-voltage incoming cabinet is turned to maintenance, the user hangs the grounding wire. High-voltage wiring cabinets are usually not equipped with grounding switches. During maintenance, the grounding switch of the outlet cabinet at the next higher level is grounded, and the ground wire is hung on site to ensure safety. Therefore, the user's substation is a high-voltage incoming cabinet for maintenance or the user hangs the ground wire. High-voltage incoming cabinet, that is, built-in high-voltage circuit breaker, mainly opens and closes the circuit and has relay protection function.
