What are the differences between the lightning protection devices of high-rise buildings and the lightning rods invented by Franklin at that time?
The difference is that now the lightning protection device installation has further specifications, the use of international or national standards.
At the same time now in addition to the traditional external lightning protection lightning protection device (lightning rods etc.), there are a large number of internal lightning protection measures, such as: integrated wiring, shielding, equipotential connection, lightning arrester (SPD) protection, referred to as the integrated lightning protection system, than to complete many old.
Now the principle of lightning rod external lightning protection device was invented by Franklin and the edifice is the same, is the use of flash grounding device, wire and a grounding device composed by lightning arrester to accept lightning deflectors through grounding device along the discharge to reach the purpose of the protection of buildings.
