Why can lightning bolts be installed at the top of the building to prevent lightning strikes?
In theory as long as the height difference between the lightning and the building reached above the standard values, in case when the lightning strike down, first to the lightning discharge (so also called lightning arrester, lightning arrester) through connected lead the lightning current into the grounding discharge, lightning current does not pass through the building body, so buildings are protected.
But things are not necessarily according to the theory of the development of lightning will not hit the lightning rod, so now the roof of the building and installation of a lightning ring belt, in order to prevent lightning if not hit lightning, a lightning with a second line of defense, also received a million deflectors, struck by lightning lightning with the same can lead to lightning current into the grounding discharge without causing damage of ontology construction.
The lightning rod effect is to attract lightning, and make it to protect buildings from lightning.
Lightning is a conductor and should be installed in the highest office building; lightning current is, its characteristic is, will hit the minimum resistance and two recent distance objects, the lightning rod will be current into the earth, thus up protection of the
