  • Lightning protection systems have changed drastically since Benjamin Franklin first invented lighting rods in 1752. Today's systems must protect modern appliances, electrical systems and building constructions - they have to keep up with tile changing requirements of modern technology. Underwriters Laboratories Inc. (UL) keeps up with these changes.

  • This research on lightning protection systems for trees was established for the purpose of developing a better understanding of lightning protection systems specifically designed to be fitted to trees. Coming from a background in sylviculture my initial concern was to enable important and intrinsically valuable trees to be protected from damage resulting from lightning strikes. However it quickly became apparent that the protection of nearby structures and buildings that might be liable to collateral damage in the event of strike was of equal significance.

  • A lightning protection system is a system designed to protect a structure from damage due to lightning strikes by intercepting such strikes and safely passing their extremely high voltage currents to "ground". Most lightning protection systems include a network of lightning rods, metal conductors, and ground electrodes designed to provide a low resistance path to ground for potential strikes.

  • A lightning rod (AUS) or lightning conductor (UK) is a metal rod or conductor mounted on top of a building and electrically connected to the ground through a wire, to protect the building in the event of lightning. If lightning strikes the building it will preferentially strike the rod, and be conducted harmlessly to ground through the wire, instead of passing through the building, where it could start a fire or cause electrocution. A lightning rod is a single component in a lightning protection system. ...

  • Hundreds of Thousands of $$$ Worth of Network Equipment can be Rendered Junk in a Flash! The issue of protecting networks from security breaches has attracted considerable attention but organisations also need to guard against environmental risks such as lightning. Damaged or destroyed equipment, which is integrated into manufacturing or data storage processes, can cause physical damage, as well as high consequential losses due to downtime. Lightning strikes can also delay production due to data loss and damage process control computers or computer-based warehouse and storage systems.
