What does gravel help prevent inside a substation?

Gravel in a substation plays a crucial role in preventing the accumulation of water, which can create hazardous conditions, including the formation of puddles. Water can lead to several problems, such as corrosion of electrical equipment, increased risk of electrical faults, and potential hazards for personnel. By providing proper drainage, gravel helps ensure that water is redirected away from critical areas, maintaining a safer environment within the substation. The structured use of gravel allows for effective groundwater management, protecting both equipment and personnel from water-related incidents.
