A good product to cover a substation ground grid is what?

Crushed stone is an excellent product to cover a substation ground grid because it offers several important benefits for electrical safety and usability. Its angular shape aids in promoting drainage while preventing soil compaction, which can be crucial in maintaining the integrity of the ground grid. Proper drainage helps to avoid the accumulation of water, reducing the risk of corrosion and ensuring that the grounding system operates effectively.

Additionally, the use of crushed stone allows for good visibility, which can be important for maintenance and safety inspections. The stone surface provides stability for personnel working around the substation, as it offers a firm footing compared to softer materials. It also minimizes vegetation growth, which can interfere with the functionality of the ground grid by obstructing visibility and potentially creating grounding issues through vegetation decay.

In summary, crushed stone balances functional requirements, safety priorities, and maintenance concerns effectively, making it the most suitable option for covering a substation ground grid.
