Distribution System Grounding
It is recommended to ground the neutral at various strategic locations in distribution substations, overhead lines and underground cables, distribution transformers, and all loads.
Repeated grounding of the three-level distribution box
Repeated grounding means that the grounding flat steel (concealed installation) or galvanized screw (surface installation) on the enclosure of the distribution box is connected to the grounding grid.
DISTRIBUTION BOX
Attach a second grounding wire from the mounting plate (B), to the factory central grounding point. The ground resistance between all system parts shall be < 0.1 Ohm.

Repeated grounding of the three-level distribution box
Once the short-circuit fault occurs, the repeated grounding resistance and the working grounding resistance form a parallel circuit, the line resistance is reduced, and the. This Grounding Standard
Grounding Requirements for Electrical Cables, Cable Trays, and
Guidelines for grounding electrical cables, busbars, and cable trays in wiring projects, ensuring safety and compliance with industry standards.
Repeated grounding
3. Repeated grounding means that in a system where the neutral point is directly grounded, a metal wire is used to connect the grounding device at one or more places of the neutral main line.
Grounding Paper
Effective grounding, or earthing, of the distribution system neutral is necessary to achieve several objectives, the most important of which is the safety of the public and utility personnel. The
