  • Substation Grounding: Role of Crushed Rock – Voltage Disturbance

    By using high resistivity crushed rock in substations, exposure current to workers during fault conditions can be reduced. 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.

    02/15/2009 2:51 AM. The purpose of crushed stones in power substations, usually about 0.08–0.15 m (3–6 in) in depth, is to retard the evaporation of soil moisture especially during dry seasons. Also, covering the surface with a material of high resistivity is very valuable in reducing shock currents. The value of this layer in reducing
