What Is "Induced Atmospheric Vibration"?

$\begingroup$ Anyone who’s had to build a power system rapidly learns that electricity is not as simple as “electrons move, work gets done”. Real electrical systems have to deal with issues of reactance and other exciting math-heavy constructs designed to drive you into some other field of study. Power Grids experience this on an epic scale. They have to concern themselves with a few needs simultaneously: ensuring electrical potential doesn’t sag under load (maintaining voltage) ensuring the integrity of the AC waveform (maintaining frequency) ensuring the system doesn’t lose too much energy to fighting its own electromagnetic behavior (controlling the power factor) That last one is the part that is profoundly nonintuitive. Capacitance and inductance inherent to the system create a sort of inertia in the system that must be fought to provide those other two guarantees. Together they work to create what’s called “reactance”. Long range lines and the equipment they connect to can ... Read full article.
