Electrostatic shielding is the phenomenon of protecting a certain region of space from external electric field .
The electric field inside a conductor is zero.
therefore to protect delicate instrumats from external electric field , we enclose them in hollow electric fields, we encloses them in hollow conductor.
In a thunderstorm accompanied by lightening , it is safer to be inside a car or a bus than to be in the open ground or under a tree.
No electrostatic potential is constant through out the volume of the conductor and has the same values as on its surface .

If a conductor having a cavity inside it is given some charge or it is placed inside the electric field then the electric field vanishes inside the cavity. This is known as electrostatic shielding.
When a charge is kept in the cavity of a conductor then it is fully appears to be resting on the outer surface. this is because of the induction i.e., the charge induces equal and opposite charge on the inner and outer surface of the conductor In this process the net charge inside the cavity becomes zero.
