The cost transfer idea states that a lightning strike to some secured composition could be prevented by cutting down the electrical possible among the secured composition and also the thundercloud. This can be performed by transferring electric powered demand (including with the close by Earth into the sky or vice versa).[27][28] Transferring electric demand from the Earth towards the sky is done by setting up engineered products made up of lots of details previously mentioned the structure.

The primary reason of those balls, however, is to supply proof of the lightning strike by shattering or falling off. If after a storm a ball is found out missing or damaged, the property owner really should then Verify the constructing, rod, and grounding wire for damage.
