Passive systems are relatively inexpensive to install and with regular inspect/maintenance can easily last the life of the building they are installed on.
A financial benefit of a passive system is there is little to wrong, the lightning conductor itself is a sturdy unit as you can imagine. The grounding points are equally robust so it is the conductor cables that require the closest inspection. The conductor cables need to be of low impedance to work efficiently and reduce the risk of damage to electronic devices.
Some structures are fitted with an external wire mesh, or Faraday cage which, can further reduce the risk of harm to not only the structure of the building but also the contents and occupants. The Faraday cage works by distributing the electrical charge around the exterior of the cage, so the massive charge from the lightning leaves the interior of the ‘cage’ unharmed.
The principal of the Faraday cage was adapted by Dr Austin Richards to create a Faraday suit. From this point he used a Tesla coil to create a show called Dr Megavolt.
