What is Reducing Ground Resistance in Substations about?

A new method is proposed to decrease ground resistances in high resistivity soil regions. The method involves three steps: 1) Drilling deep holes in the ground 2) Developing cracks in the soil around the holes using explosions 3) Filling the holes and cracks with low resistivity materials under pressure This forms a complex network of cracks filled with low resistivity material connected to the substation grounding grid, decreasing the overall ground resistance. Application of this method can help power s
