Stones in switchyard

 way are stones layed in switchyard:

Stones, often called gravel or ballast, are laid in switchyards (electrical substations) for several important reasons:

1. Insulation:

 Stones provide an insulating layer to prevent step and touch potential, reducing the risk of electrical shock to personnel. This is crucial in high-voltage environments where grounding can be a significant safety concern.

2. Drainage:

 Stones facilitate good drainage, preventing water from accumulating around electrical equipment, which can cause corrosion or short circuits.

3. Weed Control:

The stones help prevent the growth of vegetation, which can obstruct access to equipment and create fire hazards.

4.Stability:

The gravel bed provides a stable surface for heavy electrical equipment, reducing the risk of movement or settling.

5.Fire Prevention:

Stones are non-flammable, reducing the risk of fire spreading within the switchyard, especially if there's a short circuit or equipment failure.

These benefits make gravel an essential part of switchyard design, enhancing safety, functionality, and maintenance.
