Induced atmospheric vibration was the cause of the Spanish power outage ...Middle East

The Portuguese grid operator -- REN -- is out with a diagnosis of what happened with the huge power outage today:

That's fascinating.

Here is how DeepSeek explains it:

Induced Atmospheric Vibration (IAV) in high-voltage power lines refers to low-frequency oscillations (typically 0.1–10 Hz) caused by corona discharge effects near the conductors. Here’s a brief breakdown:

Cause:

When high-voltage lines operate near their corona inception threshold, ionization of surrounding air molecules occurs, creating space charges (ions and electrons).

Under certain conditions (e.g., high humidity, rough conductor surfaces), these charges interact with the electric field, generating periodic electrohydrodynamic (EHD) forces.

Mechanism:

The EHD forces induce pressure waves in the air, causing vibrations in the conductor or nearby objects (e.g., insulators).

Unlike aeolian vibration (caused by wind) or galloping (large-amplitude motion), IAV is driven purely by electrical-atmospheric coupling.

Effects:

Usually low amplitude but can contribute to fatigue over time.

May exacerbate other vibration modes or cause audible hum.

Mitigation:

Smooth conductor surfaces (e.g., polished or coated wires).

Optimized voltage gradients to minimize corona.

IAV is less common than mechanical vibrations but is studied for its unique electromechanical interactions. ...

The vibrations can lead to fatigue cracks and loosened hardware.
