Everything you need to know about the lightning and radio frequency bonding requirements in military and aerospace standards (and nothing you don’t!)
The most common characterization of ground rods actually differs from what is observed in the case of lightning. This article discusses what is observed and how that affects ground rod performance.
The evolution of E and H fields on aircraft struck by lightning is a complex process. An October 2014 in-flight lightning strike is reviewed in this article as an example that inspires a fresh look at how lightning E and H fields should be considered for indirect effects certification.
Why the effects of nearby lightning might be over-estimated, or in some cases underestimated, and how to get more realistic estimates.
Why hasn’t multi-burst testing to simulate lightning been more widely done? And why hasn’t it made its way into standards?
Known mechanisms that couple lightning surges onto communication cables, and how these mechanisms apply for the specific case of Ethernet cabling.
A million volts and 25 thousand amps are generated during a typical lightning strike. The phenomenology of nature’s oldest EMI Beast is quite fascinating, notably the physics that govern the discharge as it approaches the ground.
Intentionally zapping nuclear weapons with lightning sounds dangerous, but it’s actually a safety precaution. Researchers at Sandia National Laboratories perform tests to ensure that stockpiles of nuclear weapons will remain safe even if lightning directly strikes the weapons.
Generally the effect of lightning on an information and technology (ICT) loop that we worry about most is damage. Let’s consider an ICT loop that is probably the most exposed to the effects of lightning – one that runs between structures.
On August 17th lightning struck Google’s data center in Belgium four times. Despite the building’s secondary power system and the servers having battery backups, a few of Google’s customers still permanently lo... Read More...
