@DeltaWye These videos really let one know just how much precision is required for high voltage connections, something I certainly wasn’t aware of. I guess all the polishing is to prevent corona effects? Also, they really show that these are truly are transmission lines in the wave guide sense. Some of it reminded me of terminating coax, back in the day

@FurryBeta @DeltaWye yes one really needs to be careful with the geometry at these higher voltages, because strong E-fields lead to breakdown (since E = V/d).

@FurryBeta @DeltaWye and telegrapher’s equations are especially important considerations in long transmission lines, as switching harmonics or lightning impulses can create overvoltages due to reflections at the boundaries. If memory serves, there is grading close to a feeder that helps mitigate this, but it’s a tricky problem to impedance match when you’re ultimately connecting to a busbar…

@emilvolk To say power engineering, and fields and waves, were not my forte, would be an understatement. Which was a real shame because it was interesting to me, but I couldn’t get my head wrapped around it. As it turned out, I spent 33 years in the power industry, but in the DCS field engineering side. Anything over 120VAC was left to someone else! @DeltaWye

@FurryBeta
I mean not many power engineers are familiar with the PDEs of traveling wave mechanics (unless they’ve also done a lot in depth on radio electronics, acoustics, or have a desire to do hardcore math). But it all goes back to Daddy Heaviside in the end.
