This article explains how to protect electrical systems from lightning related damage and how to assess the degree of risk in a given environment.

This article explains how to effectively use lightning arresters to divert the effects of short-term overvoltages on an electrical system resulting from lightning. It is important to understand classes and ratings of lightning arresters to get proper lightning protection.

A lightning transient is very short in duration and won't really affect the rms value to the amount shown on these charts. However, there may be something associated with a limit on the input circuits to the instrument that make it show up this way. The sampling rate of the instrument will also be an important factor in the correct calculation of the rms voltage, including a lightning transient.

This article provides a list of checkpoints to prevent lightning-induced damage including securing the grounding electrode system, checking bonding between grounding electrodes, connections between buildings and ensuring proper surge protection.

This article provides instructions for establishing a line of defense against lightning-induced overvoltages by installing surge arresters.

No region of North America receives more lightning strikes than central Florida. With more than 100 days of severe thunderstorms every year, the area from Jacksonville to Tampa is justifiably known as the lightning capital of the world. You don't want to be caught on the golf course swinging your 9-iron when one of those electrical storms comes rumbling by. And it can be a tough place to operate a business — especially one that relies on sensitive electronic equipment. That is, unless you've invested in adequate lightning and surge protection equipment and a reliable low-resistance, low-impedance grounding system.

This article provides information about lightning-induced damage risks as well as topics including charge neutralization, electromagnetic pulses and the cost of downtime.

This entry tells the story of a power plant in Wisconsin knocked out of service by a lightning strike. The damage done resulted in $8.3 million in repairs and could have been prevented had the plant employed proper lightning damage prevention.

The Lightning Protection Institute is a non-profit organization that offers information on lightning protection including a directory of hardware installers, seminar information, public service announcements and a directory of architects and engineering services.

This article explains the need for lightning protection, how a lightning protection system works, and how to protect a building from lightning using a UL certified protection system.

This article covers an extensive amount of lightning protection information from lightning rods to transients and surges as well as downconductors, grounding methods, detection and testing.

This compilation of articles provides a wealth of information regarding lightning protection including articles on lightning protection for amateur radio stations, why lightning protection is necessary and lightning protection specifications.

This link is UL's explanation of lightning protection systems and how UL-certified systems prevent loss by minimizing the risk of lightning-induced damages as well as providing consumers with a tool to make informed choices when selecting equipment and equipment installer.

This article provides a general overview of how lightning protection systems works as well as the components of a lightning protection system, surge protectors, lightning dissipation and other lightning protection facts.

This article from Inspectapedia offers a variety of information about lightning protection systems including where and why lightning strikes, examples of lightning-related fire damage, how lightning protection systems work, how to inspect them and where to buy them.

ULPA is an association of lightning protection manufacturers, contractors, technicians and engineers dedicated to promoting lightning protection compliant with nationally recognized safety standards set by the Lightning Protection Institute, the National Fire Protection Association and Underwriters Laboratories.

It is well established that properly installed and maintained conventional structural lightning protection systems (LPS) based on Franklin's methods significantly decrease lightning damage. However, the installation of such a system in conformance with NFPA 780 is not a simple matter. Proper procedures must be followed for the protection to be effective. Non-experts need guidance as provided by an appropriate standard which, in the United States, is contained in NFPA 780. Most architects and builders do not have the expertise to evaluate competing LPS designs. In this area (and many others), they depend on accepted standards to provide the guidance needed to properly design and install LPSs, confident that the standard has been appropriately reviewed and approved.

This link contains a list of articles about proper lightning protection for amateur radio enthusiasts.

This page provides information on lightning safety when the risk of lightning becomes imminent for both indoor and outdoor situations.

This basic overview of lightning describes why lightning occurs, types of lightning, ground flashes and thunder.
