franklin simple rod lightning rods (Franklin points) are primarily used to protect structures and people from lightning strikes. Placed on the roofs of buildings, they intercept lightning, thus preventing direct hits. They then safely dissipate the electrical energy of the lightning to the ground. This is done through a conductor down conductor and grounding system in accordance with IEC 62305.
Furthermore, a Faraday cage, made of a conductor mesh, blocks external electric fields. By canceling these fields internally, it offers additional protection, useful in laboratories or for sensitive equipment. Sometimes, franklin simple rod are used in conjunction with a mesh or Faraday cage, reinforcing protection for tall or particularly exposed structures.
However, the protection area of franklin simple rod is more limited compared to Early Streamer Emission (ESE) lightning rods. The latter, with their advanced interception capabilities, cover a larger area. ESE rods actively react to the precursors of lightning, providing a superior protection surface.
