Failures Caused by Ground Potential Rise (GPR) at Interconnected Houses

Much has been written about failures due to ground potential rise (GPR), generally in connection with single houses with multiple grounds. But in cases where multiple houses are interconnected via a single piece of equipment, equipment failures could be caused by insulation issues due to GPR attributable to lightning.

Electrical Fire Patterns in Vegetation

The formation of branching patterns is commonly associated with electrical discharges. Lightning and electrostatic discharges from a Van de Graaff generator are transient luminous branching patterns, and sometimes the passing of an electrical current leaves residual physical patterns. Examples of how such patterns are formed are presented.

Lightning and RF Electrical Bonding

Everything you need to know about the lightning and radio frequency bonding requirements in military and aerospace standards (and nothing you don’t!)

How Grounds Affect the Peak Voltage Due to Lightning

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.

New Lightning Hazards to Consider for Aircraft Certification

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.

Do Classical Calculations of Induction Due to Nearby Lightning Give Misleading Results?

Why the effects of nearby lightning might be over-estimated, or in some cases underestimated, and how to get more realistic estimates.

Effect of Multi-Burst Lightning Flashes on Surge Protective Devices Using MOVs

Why hasn’t multi-burst testing to simulate lightning been more widely done? And why hasn’t it made its way into standards?

Designing Ethernet Cable Ports to Withstand Lightning Surges

Known mechanisms that couple lightning surges onto communication cables, and how these mechanisms apply for the specific case of Ethernet cabling.

Lightning Catches Bullet

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.

What Happens When Lightning Strikes a Nuclear Weapon?

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.
