What are the basic components of a lightning protection system?
A lightning protection system consists of the following five parts: air terminals (lightning rods), conductors, ground connections (electrodes), bonding, and lightning arrestors.
What are lightning protection systems?
What Are Lightning Protection Systems? A lightning protection system provides a safe pathway for energy from a lightning strike to find its way to earth, encouraging the bolt to bypass building components that might otherwise be damaged.
How do you protect a metal building from lightning?
Metal roofs do not attract lightning strikes; nor do metal roofs protect a building against lightning. The only way to protect a building is with a properly designed and installed lightning protection system (LPS).
What is a lightning arrestor made of?
Lightning arresters used in power substations are large devices, consisting of a porcelain tube several feet long and several inches in diameter, typically filled with discs of zinc oxide. A safety port on the side of the device vents the occasional internal explosion without shattering the porcelain cylinder.
How do lightning protection systems protect structures?
A lightning protection system is designed to protect a structure from damage by intercepting such strikes and safely passing their extremely high voltage currents to "ground." This system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground ...
What are three parts of a lightning protection system for a building?
The parts of a lightning protection system are air terminals (lightning rods or strike termination devices), bonding conductors, ground terminals (ground or "earthing" rods, plates, or mesh), and all of the connectors and supports to complete the system.
What are the 2 main ways a lightning rod protects a building?
Franklin suggested that a lightning rod protects a building by one of two methods. First, the rod serves to prevent a charged cloud from releasing a bolt of lightning. And second, the lightning rod serves to safely divert the lightning to the ground in event that the cloud does discharge its lightning via a bolt.
Do lightning rod systems work?
Lightning rods intercept this voltage, providing a safe path for lightning current into the ground. They do not decrease the likelihood your home may be struck, but provide a direct path to ground, preventing damage to your home from fire, explosion, and electrical surges that can result from lightning strikes.
Do metal buildings need lightning protection?
Contrary to popular myth, metal buildings are not more dangerous during lightning storms–in fact, metal buildings can technically be safer due to the decreased risk of fires and explosions in metal buildings, thanks to the fact that metal makes for an excellent electrical conductor when compared to other materials.
What happens when lightning hits a metal building?
In the case of a metal roofed building, any electricity from a lightning strike will be safely transferred to the ground below so occupants will be unaffected. Plus, metal's inflammable nature means your home will be even more safe should the rare chance of a lightning strike actually take place.
Are metal buildings safe from lightning?
Conductible Steel Buildings Resist Lightning Damage
The less the resistance to electricity, the less likely structural damage will occur. Steel conducts current far better than wood. Properly grounded, a metal building permits lightning current to pass harmlessly through the framing and into the ground.
How many types of lightning protection systems are there?
The 3 types of lightning protection system.
Why do lightning rods have glass balls?
Lightning rods were embellished with ornamental glass balls (now prized by collectors). ... The main purpose of these balls, however, was to provide evidence of a lightning strike by shattering or falling off.
What is Rod gap diverter?
Rod Gap Arrester: This is the simplest form of surge diverter consisting of two 12 mm dia or square with ends facing each other, one connected to line and the second connected to earth. These are usually connected across the bushings of various equipments.
