A thin layer of crushed stone or gravel spread over the substation surface substantially increases R F, the resistance between surface soil and a person’s feet. Crushed stone has higher resistivity than surface soil, and so the potentially dangerous ground current remains confined to surface soil and isolated from a worker’s or passerby’s feet. There will be very little current in the
