Answer / vikramsimha reddy
if grass is grown,moisture deposits on the surface of ground
and grass in the areas of moist weather or during winters
which posses harm if any short circuit occurs..
stones or gravel is used
Gravel/Stones in the substation is provided to reduce the
step potential and touch potential when operators work on
switch yard.
Step potential : It is the potential developed between the
two feet on the ground of a man or animal when short circuit
occurs. This results in flow of current in the body leads to
electrical shock
Touch potential: It is the potential that is developed
between the ground and the body of the equipment when a
person touches the body during fault condition. When
operating personnel touch an electrical equipment during
short circuit condition, fault current flows through the
human body. This is defined as touch potential.
Stones eliminate the growth of small weeds and plants inside
the switch yard

Answer / mohammad al fahel
because of the magnetic field since transmission line is high voltage it reaches up to 400 KV so it has a high magnetic field which is harmfull for all creatures for humans and plants , but if you want to plant grass i think its fine since the effective of it is not that big
