How is Mesh Protection for lightning done ?

The mesh method of lightning protection is a method of protecting buildings.  The mesh method involves enclosing the building inside a metallic cage.  The cage is also known as a faraday's cage.  The mesh method
works by ensuring that the lightning which strikes the building always flows on the outside through the metal cage.  Hence, no damage is done to the building.

The mesh method cannot be used in circular surfaces.  The number and distance between the conductors in the mesh method needs to be calculated.
