Lightning rods or 'air terminals' are only a small part of a complete lightning protection system. In fact, the rods may play the least important role in a system installation. A lightning protection system is composed of three main components: 1. Rods or 'Air Terminals'- The small, vertical protrusions designed to act as the 'terminal' for a light...
A lightning protection system's only purpose is to ensure safety to a building and its occupants if lightning happens to hit it directly, a task accomplished by providing a good, safe path to ground for the lightning to follow. Contrary to the myths, lightning protection systems: 1. Don'tattract lightning 2. Don't and cannotdissipate or prevent lig...
Without a designated path to reach ground, a lightning strike may choose to instead utilize any conductor available inside a house or building. This may include the phone, cable, or electrical lines, the water or gas pipes, or (in the case of a steel-framed building) the structure itself. Lightning usually will follow one or more of these paths to ...
Surge protectors and UPS units are not suitable lightning protection devices. These appliances provide some degree of protection from voltage spikes from everyday power surges and distant lightning strikes. But when lightning strikes a structure directly or very close to it, lightning protection system or not, all bets are off. A common surge prote...
Products called 'lightning elimination' or 'lightning dissipation' devices have arisen as a result of two myths: one, that a thunderstorm's charge can be drained or otherwise affected by objects on the ground, and two, cloud-to-ground lightning discharges begin from the ground. These products, that are still being sold today, claim to be able to pr...
Rods and protection systems don't attract lightning, nor do they influence where lightning will strike. Rods or protection systems do not and cannot prevent lightning, nor can they 'discharge' thunderstorms. Lightning protection systems (including placement of rods, cables, and groundings) are custom-designed for individual structures and require c...
Sep 19, 2016 · Lightning protection systems are designed first and foremost as fire protection systems – to stop the building from burning down and losing the people and equipment inside. Bringing metallic services into a structure provides paths for lightning to follow from the outside environment to create hazards within.
A lightning protection system intercepts a direct lightning strike and safely discharges the lightning current to prevent fire, structural damage, or personal injury. Systems should be designed and installed to meet national safety standards.
In this lesson, you will learn the fundamentals of how lightning protection systems function. The intent of the lesson is not to discuss the detailed design requirements presented in various codes and standards for lightning protection but to understand the basic physics associated with
Jul 3, 2019 · To safeguard people and property from lightning-related hazards, NFPA 780-2020 standardizes the installation of lightning protection systems. And, these hazards are more likely than an individual being struck by lightning directly.
May 17, 2017 · Know the basics of lightning protection systems and the need for them. Understand the factors that electrical engineers should consider when assessing lightning risk. Apply the codes and standards to specifying lightning protection systems.
