Why are Stones used in Substations instead of Sand or Grass?

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 Touch Voltage which may be defined as follow:. Ground Potential Rise (GPR): The maximum electrical potential that a substation grounding grid may ...

What You Need to Know About Substations

 · The crushed stone bed provides an insulating buffer between workers and the mat. The stone layer''s resistance is sometimes 3,000 ohms/meter or more between the worker and the mat. A common question about equi-potential in substations comes up often: "Why add resistance to the mat if you want equi-potential?"

Power Substation Case Study Briefing Paper

Substations form vital nodes in the HV and EHV networks because they allow configuration changes of networks during the system operation using switching devices in modern substations controlled by computer systems. Initiation of the control procedure may be performed locally by substation operators or remotely from EPS control centres.

Use of Gravel in Electrical Substation (EHV)

 · Use of Gravel in Electrical Substation (EHV) Generally gravel size of approx. 40 mm, bed thickness of 100mm to 150mm used in and around EHV substation increases the soil resistivity in the outer layer and thus helps in reducing step and touch potential also it …

Surface Material for Substation Ground Grid

 · Crushed rock when wet has an approximate resistance of 3000 ohms/m. Asphalt when wet has a higher resisitiviey, approximately 9000 ohms/m. In either case their purpose is the same, to act as an insulator between people and the buried ground grid. For purposes of simulation I would use the worst case, crushed rock in this case.
