in rainy seasons the earths crust resistivity will be
increases due to the water may be combine with soil salts so
to avoid this we can use rocks of 40 mm to reduce the fault
current to flow through the transformer
2) due heavy load of the t/f soil can be loss its stiffness
so we use rocks
3)to prevent leakage of oil to ground nduku anthey jari padi
shock kothey chances unai so adi prevent chayadaniki soil
kana rocks chala better
