Re: Lightning Protection



The formula for the lightning protection, Franklim pole type:

Rp=h*tan A

Where Rp is the radius of protection of a cone defined by the formula, with the height h in meters (h is the top point of the pole) and A is the angle in degrees at the top, that usually is 55º for a class IV degree of protection.

For an electronic protection pole, the formula is rader complicated, and for that you should contact the manufacters because they have tables for each equipment.
