Zonal Lighting system are used
to protect the house from the thunderous and disastrous effects of
lightning. Lighting protection system provides a means for
controlling it and preventing damage by providing a low resistance
path for the discharge of lightning energy. One needs to be very
careful while designing a lighting control system as a wrong one may
cause more damage to the building. These days, rods are used on the
top of the buildings that are connected to the faraday cage to the
ground. Such systems wait for the lightning to strike one of the
rods to get grounded. Due to the velocity and undefined path, safety
provided by this system is ineffective and Unreliable. Lightning is
supposed to strike at buildings and other things like, such as a
tree touching a high tension power line), thus producing very high
voltages which has very bad effect on property such as following
underground tree roots, metal porch railings, and copper or steel
building water pipes. modern lightning rods have a short blunt tip
and that they are connected to earth by heavy metal cables. |
