Substation Grounding: Role of Crushed Rock - Voltage Disturbance

Crushed rock is useful in reducing step and touch potentials. Resistivity value of crushed rock depends on many factors such as type of locally available material, size of stone, washed vs un-washed stone etc. Washed rocks have less dust and has more resistivity compared to un-washed ones. Removing dust also aids in faster drying time after a rain.
