I know it's off-topic but what do you mean by "funny things"?
3 Phase high voltage overheads do "funny things"....
They have electromagnetic, inductive, and capacitive (sp???) effeccts on each other, and the geometry of them effects how they interact.
By having an adjacent 120 degree out of phase conductor next to it, there will be an induced current/voltage, the makes the sinusoidal waves non sinusoidal, introducing "noise" that heats up transformers and things...it can make one phase a higher voltage than the others...on an unloaded line, it can actually make the voltage at the other end HIGHER than the starting voltage, especially if there's no load at the other end, and you want to close a breaker in to a load.
So if you watch them, as you drive distances, depending on the voltage (spacing), and geometry, you can observe the workarounds.
So 11kV lines have a fairly small spacing requirement to prevent flashing, so they "phase swap" as they go across the distance, you can see one phase lifted, crossed to the other side, high, then a phase on that side swapped to the other, before the high wire drops down, over three or four power poles - roatating the phases means that the impact on one phase on the others gets negated over distance.
On the BIG HV towers, they often can't do that, so might have one phase on the two conductors on the middle deck then have one high, one low for the other two phases.
The loading/unloading causes issues...and creating a system that carries 24 hours worth of energy over 8 hours, before being unloaded for the remaining 16 is a problematic design.
I had a paper here somewhere on an isolated community in Canada somewhere that had a small (10s of MW) coal generating station locally, and a transmission line that stretcht to the main grid...they decommissioned the coal generator, as the grid could supply the load easily, however they were restricted to only 10s of percent of the line capacity due to the long transmission line messing the power distribution up. So they had to cut the shaft on the turbine generator, and run the generator at 3,600RPM, and connected to the grid like a generator (in a form called a synchronous condenser - condenser baing an ancient term for capacitor), which corrected out the capacitance issues, and allowed the line to be fully loaded.
Wind and solar farms are crying foul that their "cheap" power is being made more expensive by having to install these at wind/solar farms.
