Stones are used instead of sand or grass in Electrical substations (Switch yards) because of following reasons: 1. During Short circuit, Step and Touch potential increase. Step potential : It is the potential developed between the two feet on the ground of a man or animal when short circuit occurs.
Stones in the substation is provided to reduce the step potential and touch potential when operators work on switch yard. Step and touch potential occurs due to the short circuit current flows on the conductor.
Acid rainwater is a conductor of electricity. As a result, the stones act as an obstacle to protect direct contact of the substation from the rainwater. Thus, by increasing the resistance, the flow of electricity is reduced. The transformers that are present in a substation are usually having a very high power rating.
Q: How are stones used in an electrical substation switchyard? A: Stones are often laid in the switchyard of an electrical substation as part of the earthing system. They are spread on the ground around the electrical …
The stones used in substations serve as an insulating layer that reduces the chance of unintended contact with the electrical potential of the ground. They help dissipate electricity evenly and prevent it from causing harm, particularly in the event of equipment failure or lightning strikes.
Within the substation, stones can serve a number of functions, such as a surface material, a base layer for the equipment, or a drainage system. Because of its adaptability, it may be a sensible option for various substation …
The switchyard has oil-filled transformers inside it. The spilled oil seeps through the grit /stone and does not remain on the upper surface. Thus in case of fire, the upper area does not catch fire and thus prevents the spreading of fire in the …

Why are gravel stones used in substation yard? The layers of Gravels avoid growth of plants and weeds in the substation yard to some extent. Generally 20 to 25mm gravel stones are used instead big size stones to facilitate movement of persons and equipment in the substation yard.
Q: How are stones used in an electrical substation switchyard? A: Stones are often laid in the switchyard of an electrical substation as part of the earthing system. They are spread on the ground around the electrical equipment, transformers, and other components.
There are multiple factors to use stones in the switchyard while designing of multiple earthing and grounding in a substation grid. The main reason to lay gravel in the substation yard is to reduce Ground Potential Rise (GPR) AKA Step Voltage and …

There are many reasons why Power Substations uses stones in the switch yard, here are some of the reasons; Stone increases the resistance between our feet and the ground. Stones prevent the accumulation of rainwater in the switch …
Why Stones are Used in Substation ? Their design and maintenance are vital for the overall system's reliability and safety. One intriguing aspect that often catches the eye is the extensive use of stones in these facilities. Let's delve into the reasons why stones are such an integral part of transformer yards and switchyards. 1.
Stones in the substation is provided to reduce the step potential and touch potential when operators work on switchyard. Step Voltage (Es) is defined as the maximum potential difference that exists between the feet when a fault current flows in the body.
Grit in the electrical switchyard is laid to make the upper surface of the soil more resistive. The more resistivity of the soil decreases the step and touch potential. The reduced step and touch potential reduce the possibility of an electric shock.
There are many reptiles like lizards, rats, chameleons, snakes, etc which find it very difficult to pass through the stones. As they are reptiles, they move only over grounds. So the stones act as the resistance in this case.
Stones in the substation is provided to reduce the step potential and touch potential when operators work on switch yard. Step and touch potential occurs due to the short circuit current …
Within the substation, stones can serve a number of functions, such as a surface material, a base layer for the equipment, or a drainage system. Because of its adaptability, it may be a sensible option for various substation designs and configurations.
Why Stones is used in Electrical Switchyard & Transformer Yard: [wp_ad_camp_2] Reasons for using Stones is used in Electrical Switchyard & Transformer Yard: Stones in the substation is provided to reduce the step potential and touch potential when operators work on switch yard.
Top 20 Reasons Why Gravel Or Stones Are Used In Substations. 20. Versatility: Within the substation, stones can serve a number of functions, such as a surface material, a base layer for the equipment, or a drainage system.
