Great feat of engineering.
RE: superconducting transmission line
A very interesting project indeed.
Thanks for the link.

Any chance you can share what sort tests were conducted ?

There was a 34kV HTS installation in Albany NY a couple of years ago. We supplied an AC supply and HV Bridge so others could perform periodic PF tests as the cable was brought to final temp over a long period of time. I believe a DC test was performed prior to installation on that project.

This is indeed an amazing development by US engineers. Kudos to them.

New generation!!!! Next step: transformer and generator?

We did perform PD testing during the 60Hz AC acceptance test on the 138kV circuit.
Regarding the DC acceptance test on the 34kV circuit, they may have had other concerns besides PD on a cable of this type. The insulation is not extruded and is operating at 65 Kelvin. I assume the possibility of space charges left over from DC testing was not a priority. I believe the mechanical stresses involved with the extreme low temperatures may be a bigger concern.
I will say the plumbing work involved with the cooling on both projects was very impressive!

Used to be if a super superconducting cable got over amped -> the B-field got too large -> the cable went non-SC exploding at the first spot that went non-SC.
Now they're saying that it's a feature that limits damage and doesn't hurt the cable.

Sounds good, I missed the 34kV part.
