There are lots of books on the subject and plenty of examples
visible around major electrical installations of how to prevent damage by
lightning. Lightning occurs when there is a large charge difference
present, normally caused by rain carrying electrons from clouds to ground.
If there is no path to deplete the charge and when the charge is great
enough, the electrons go back to the more positively charged area of the
clouds above. The strike is from ground to cloud. The use of several
ground rods tied together and connected to power grounds, water pipes, gas
pipes, and the antenna system tends to deplete the charge to the earth,
preventing the strike. Unplug, disconnect and ground your equipment.
During an electrical storm stay away from doors, windows and chimneys. Get
in your vehicle and close the doors.
Safety!
