Ideal Transformer with Superconductors?

Click For Summary
SUMMARY

Encasing a transformer entirely in superconducting material significantly enhances its efficiency, moving it closer to the ideal transformer concept. This design eliminates resistive losses (I²R) in the windings, although hysteresis and eddy current losses in the core remain. The proposed configuration, with insulated superconducting materials for the core, windings, and casing, minimizes magnetic flux leakage, yet some leakage inductance persists due to imperfect coupling between the primary and secondary coils. Overall, this approach represents a notable improvement in transformer design.

Just had an idea that raised a few questions and I can't find any relevant data on after a bit of searching so thought I'd ask here. If you were to make a transformer entirely encased in superconducting material would it result in a significant step toward and ideal transformer or is magnetic flux confinement not that much of an issue? Would it have any noticeable change? What if you were to make everything out of insulated superconducting materials (the core, the windings and a case to ensure none of the magnetic flux escaped)? If it makes a difference, please assume the casing would be deposited directly against the windings and core insulation so all that actually exists between the different components would be insulation of negligable thickness (just enough to avoid arcing).

Such a design would eliminate loss due to I2R in the windings. But the core material would still incur hysteresis & eddy current losses. Another issue is that of leakage flux. Since the 2 windings cannot perfectly couple, there will still be some leakage inductance, i.e. not all primary coil flux links the secondary coil, & vice-versa.

But it is definitely an improvement.
