Re:How to ramp up a factory consuming a lot of energy? by londons_explore on Monday June 19, 2023 @01:19PM (#36393765)
In reality, the phase difference is always small, and it ends up not mattering.

But... If you had a worldwide electricity grid running at 60Hz, it would start to matter, and you would make sure to use local capacitors/inductors to make phase shifts to make sure that you didn't have big circulating currents in loops (they just are wasting energy)

Napkin math: Speed of light is 300,000 kilometers/second. At 60 hz, the wavelength would be 5,000 km. 1% of that would be 50 km.

Imagine a triangle with 2 generators 100km apart, and a factory almost due south of one generator:

ga ......... gb

__f

I think the offset would be something like sin(gb.f) - sin(ga.f)

But really this comment is bait for an EE to school me.
