RE: Substation Grading
From the civil engineering standpoint, crushed rock may be use as soil stabilizer, internal roadway, sub drainage, etc.
Crushed stone # 2 without fines material is expected to have a wet resistivity around 2000 to 3000 Ohm-meter. A layer of 4 inches inside the substation and 3 ft beyond the fence usually provide may have good results.
