Lightning Air Terminal – Franklin Rod

Faraday Cage projects require lightning rods, which are crucial in rolling sphere calculations according to IEC 62305 standards, to be manufactured in accordance with IEC 50164 standards and tested in laboratory conditions for discharges up to 100 kA. The tip dimensions can range from 1 meter to 12 meters depending on system design. Here, the height of the structure and the final roof elevations are important in system design. Additionally, the S protection distance is significant for the tip lengths. Protection of tall buildings, flammable gas tanks, or solar panels can be provided with lightning rods. The variety of down conductor systems and insulated surfaces also affects the choice of the lightning rod tip.

Of course, the lightning rod tip and the rolling sphere calculations depend on the risk analysis of the facility to be protected. Spheres tangential to the tip create protected zones in the design. The topic and calculations are extensive, so a thorough understanding of IEC 62305 standards and calculation methods is essential.

For example, lightning rods generally installed on rooftops must also be placed on the sides of structures and towers exceeding 60 meters. High structures like the Eiffel Tower are protected in this way. Lightning rods can also be designed according to the cone method parallel to the rolling sphere method in direct type systems. Using the formula below and our risk analysis table, the protection angle of the lightning rod tip can be calculated. During installation, metal surfaces must strictly observe the S separation distance.
