Any metallic physique 3/16” thick or more projecting over a structure will accept a lightning strike devoid of burning as a result of. Hence, occasionally construction factors could be incorporated as strike terminations.
Building a technique of air terminals projecting only 10 inches higher than these structural details of emphasis and alongside ridges and edges continues to be verified, in greater than a century of observe, to supply interception of some ninety five% of recorded lightning flashes, such as the most violent. Some reduced potential lightning strokes could theoretically connect on flat planes away from strike terminations designed to the Criteria, but the consequences are within just satisfactory limits for ordinary construction. Thinking of the lessen Vitality stage demanded for a bypass, the other structural grounding parts A part of a complete lightning defense system, and the random likelihood for reference to a procedure element in any case, this method of making protection is considered most economical.

When it begins, a lightning bolt travels by a downward tracer which propagates in jumps in any course.
It Is that this progress time that establishes the radius of protection: the even more the upward tracer emitted via the lightning rod is Superior, the greater the height at which it is going to seize the downward lightning tracer, and therefore the higher the safeguarded lightning strike place.
